NASA | A Black Widow Pulsar Consumes its Mate
Vložit

- Black widow spiders and their Australian cousins, known as redbacks, are notorious for an unsettling tendency to kill and devour their male partners. Astronomers have noted similar behavior among two rare breeds of binary system that contain rapidly spinning neutron stars, also known as pulsars.
The essential features of black widow and redback binaries are that they place a normal but very low-mass star in close proximity to a millisecond pulsar, which has disastrous consequences for the star. Black widow systems contain stars that are both physically smaller and of much lower mass than those found in redbacks.
So far, astronomers have found at least 18 black widows and nine redbacks within the Milky Way, and additional members of each class have been discovered within the dense globular star clusters that orbit our galaxy.
One black widow system, named PSR J1311-3430 and discovered in 2012, sets the record for the tightest orbit of its class and contains one of the heaviest neutron stars known. The pulsar's featherweight companion, which is only a dozen or so times the mass of Jupiter and just 60 percent of its size, completes an orbit every 93 minutes -- less time than it takes to watch most movies.
The side of the star facing the pulsar is heated to more than 21,000 degrees Fahrenheit (nearly 12,000 C), or more than twice as hot as the sun's surface. Recent studies allow a range of values extending down to 2 solar masses for the pulsar, making it one of the most massive neutron stars known.
Watch the video to learn more about this system and its discovery from some of the scientists involved.

Grateful to NASA Goddard for creating these videos, for sharing fascinating information with 'regular' people, and for not dumbing it down. I look forward to the next video.
I can't even picture an object spinning 700 times a second. That's just...I can't picture it.
Then try to consider the fact that the object a few times the mass of the sun. There plenty of things spinning much faster than this, but not with this mass.
+NLwino That is mind blowing.
And imagine this, the fastest man-made object ever made reached a speed of 600 MILLION rotations per minute, that's 100 MILLION rotations per second. The object was 4 micrometers large, compared to 40 micrometers, the width of a human hair. Getting a lot larger, the fastest spinning object in the universe (that I found) is a black hole spinning at around 186111 times per second (85% speed of light). Imagine THAT
That's because its moving at 24% the speed of light.
Black holes for example. However they aren't visible by any normal means. So pulsars are the fastest spinning VISIBLE objects in the universe.
That's the stuff I expect from NASA :). Thanks.
Excellent video! Thank you. Somebody put a lot of thought into the presentation, producing a little gem.
Watch this video and try to imagine the incredible physical forces at play in these twisted stellar relationships... It's mind-boggling.

"Mind-boggling", the exact words I just used to forward this video on. Would be amazing to be able to see something like this happening close up (but still from a safe distance!) Thanks for sharing.

Dear Researchers, Im sorry for commentate earlier.This is important.Great Work.God Bless you.
0:35 So mesmerizing.....Brilliant
Awesome video guys. Beautifully done too. Thanks!
Cool!
That. Was. Really interesting. Thank you, NASA Goddard
this was fucking awesome! thanks for explaining the gamma/ radio waves in such visible terms
Amazing work! Such clever people.
Great video! very interesting.
Extraordinary, and a great explanation of a potential discovery ^_^
Now thats some science. Great job!
Cuesta un poco entender la naturaleza y comportamiento de los pulsares pero este video lo explica de forma tan sencilla que es casi a prueba de tontos, muy buen reportaje, felicitaciones.
Vry knowledgeble video
That's just amazing!!
That is so crazy. The amount of energy just bursting away out there, wow. When are we building pulsar panels?
As Spock would say "Fascinating!"
So its possible this neutron star if it swallows enough additional material, would collapse into a black hole. It will be astonishing if we could one day witness that birth via observations like this.
KlunkerRider if its very gradual we might even notice a change to quarkstar and who knows - preon stars.
Some say the kilonova will result in a black hole but so far it's in supernova and could contain Gold and Plutonium.
Aww! 🥰 so cute. They’re wonderful sources of energy. Provided you can get those waves. ☺️
So cringe-y
Thanks ,very intersting!
Amazing
Just awesome!
Thanks!
Way cool. Thank you.
Love this!!!!!!
What a Strange, Violent and yet Beautiful Universe.
very cool!
Very interesting...
Incredibly Facinating
👍
Beautiful to extreme
thanks
This is awesome 🇺🇸👑💕
Beautiful 👾
If the companion to all of these pulsars are within the electromagnetic envelope of the star's immediate field, you could have a rocky or gaseous body create a coccoon of neutrally charged material floating around the equatorial region of the star, being blown out by the physical force of the star, and not aligned to either of it's poles, but there would be an expected polarity to the jets based upon the polarity of the field involved -- couldn't we use that like a cat-scan to detect the details of the neubula of gasses around it by looking at the radio emissions from the excited material as it is moved along the magnetic lines of the pulsar?
How big a radio dish would we need to see that kind of resolution on the closest pulsar? If we can study the immediate electromagnetic field of an active pulsar, we can begin to understand the mechanics of blazars and magnetars much more clearly -- and maybe black holes are black because not only is the light affected gravitationally, but electromagnetically as well, redifining the nature of a black hole as electo-magnetically and gravitationally bound physics instead of just gravity alone. We may be seeing black holes generating space by forcibly ramming light into a right angled trajectory to how a photon normally drifts through space, causing it to litterally spit out space at the speed of light instead of spitting out light; the effect would be super-luminal travel along the escape trajectory of the black hole matter itself.
If you have a spinning black hole that turns space 90 degrees with gravity, and light itself, capable of being bent by electromagnetism is turned to face completely away from an observer (a full 180 degrees), so that the chirality of the photon is showing us it's negatively polarized side, we wouldn't be able to see it, and if in fact it was the tail end of a particle accellerated to the speed of light with the travel vector sent at the observer but pointed in the same direction would create a static point of matter travelling lightspeed fast but staying in place. Do you think a standing wave of photons can create the fabric of spacetime?
"How many people really understand how much energy are being absorbed and emitted by these objects? See: Cosmic duo spins matter from light!!
The next field of theoretical physics will bring us a sort of fusion of wave and emission of Cosmic rays."
I find the current arrangement of the binary pair intriguing, especially given that the two objects are separated on the scale of the Earth-Moon system. My question is, what did this binary system look like when the pulsar was still in it's red giant phase? Wouldn't it's companion have been enveloped inside the red giant, and if so, wouldn't it have been consumed by the red giant? Perhaps the companion star was drawn in toward the pulsar over the years. Any ideas?
+Jon Christians It is quite possible that the neutron star was never in red giant phase, as it would have been a very massive star and would have exploded in a supernova in order to create the neutron star at all. If so; an equally pertinent question is what did the supernova do to the companion?
Also, it is possible that something inside a red giant could survive the entire phase. The outer layers are not very dense in a Red Giant. Apparently it is much less dense than our own atmosphere. If so, something as hardy as a star, or even a rocky planet would probably survive the whispy blowtorch for the billions of years the primary star is in the giant phase.
Lastly, yes, it sis also quite possible the neutron star captured the companion later. I think that is actually the most likely, as that system is so insanely close together given typical binary standards that I kind of doubt they formed together. Also, that would easily explain away why a giant phase or a supernova did not seem to bother the companion.
Get the SPHEROLIX of enhanced remote viewing and play it on your screen to see the actual historical phase of what U ASK!
It appears as though the axis of rotation of the pulsar is itself moving/rotating around a different axis. This seems to be the case in most representations I see. Am I right in thinking this is impossible?
That's the magnetic pole which is offset from the rotational pole.
Ahh, so the pulse emits from the magnetic pole, which is what is rotating. That would certainly explain it! Thanks
LIFE IS SHORT....
Thanks due to people such as Holger Pletsch and Roger Romano for going for the answers. Cool as solid helium, i gotta say bravo to all women and men who use intellect to shine a light on fantastic subjects such as ultra-dense matter. Major respect + keep looking out there. It's a Big Back Yard, after all!
Cheerz!
How much more mass til it collapses?
great vid, I think NASA have to do more divulgation (budgets, I know. I know...) & sorry if I lose mi mind but... can anybody make subtitle translation files (spanish is god to me!)? or even in english downloadable? anyway awesome work, Thanks!
Wow!
after watching this, and realizing the regular nature of these "normal" superdense stars, I began to think that worm holes may not exist.
What if we could use really heavy objects which produce massive gravity forces to distort time whilst traveling to other stars?
Am I right in deducing two facts:1) PULSARS are Neutron stars that rapidly rotate, thus emitting periodic flashes of ultaviolate rays, gamma rays, x rays, and other cosmic rays, etc; 2) regular Neutron stars don't rotate at all to produce regular flashing pulses, but remain relatively sedentiary to that occupied region of space whence they dwell?
>Am I right in deducing two facts:1) PULSARS are
Neutron stars that rapidly rotate, thus emitting periodic flashes of
ultaviolate rays,
>gamma rays, x rays, and other cosmic rays, etc;
Yes, except that cosmic rays are not the same thing
as light. Cosmic rays are accelerated particles, and pulsars do emit
them, but because they are electrically charged particles their paths
are also deflected by the galactic magnetic field.
We can’t link any specific cosmic rays to specific cosmic sources
except the sun. There’s more at this link:

Neutron stars all typically have detectable
pulsations since they spin rapidly and emit light in highly directed
patterns. Astronomers classify neutron stars according to the primary
power source for their emission and spin evolution. Rotation-powered
pulsars derive their energy primarily from the spin of the
neutron star, magnetars from their superstrong magnetic fields, isolated
neutron stars from the latent heat of their internal matter, and
accretion-powered neutron stars obtain energy from
matter they pull from a binary companion. In black widow systems like
the one discussed in the video, the pulsar accreted matter from its
companion, spun up its spin, increased its emissions - and then, like
its namesake spider, turned on its companion and
began evaporating it. For more on pulsars in general, visit:

Thanks for clarifying it all!
What a wonderful universe we live in.. Can't wait far a "Starship Enterprise" to be built, but I'm born a few hundred years to early for that i guess...
There must come a point at which the pulsar accretes the "straw that breaks the camels back" and goes dark and silent as its mass/density exceeds the gravitational escape velocity of electromagnetic radiation. I wonder will there be any hiatus of dimming or an instantaneous shut down?
+Ralph Latham I doubt this pulsar could accrete another solar mass to collapse it into a black hole, since its companion is very light after blasting most of its mass away.
How did the orbit around that neutron star get so tight for the companion? I mean, before the star collapsed to form a neutron star, the companion could not have existed at that radius, so it must have come after the neutron star was formed. Yet isn't there so much energy being blasted at any incoming object that it would have been deflected away?
The radio decrease in time because of emission of gravitational waves. Another more important factor is mass loss, that become in a lower spinning moment that reduces the orbit radio. When the radio become in order of relative size of stars then produce a fusion (supernova)
what if the pulsar magnetic field is destroyed by the magnetic storms
Exactly what I thought it was.
POR FAVOR COLOCAR SUBTITULOS EN ESPAÑOL.
What is the stellar mass of this neutron star? I recall that at 3 stellar masses or greater the core of a super nova will create the blackhole.
+Aidan Shaffer Between 1.6 and 2.4 solar masses.
1:29 what is a "blazar"?
He is so handsome!
could it be a quark star, this pulsar?
A Black Widow!? More like trying to maintain a relationship with a Zombie. I am convinced that Neutron Stars ARE the Zombies of the Cosmos.
fascinating...what you don't see is incredible
Are they all near the edge of, or outside a galaxy?
Are these things fairly isolated in space?
Bush Bob pulsars appears anywhere in the galaxy and outside the galaxy. They don’t have any patterns. That being said: we can’t measure them very well outside our galaxy as they are too weak and inconsistent over those distances
YEA.
Could a pulsar "normalize" over time into a conventional dwarf object as it loses energy and if no additional mass is added to it?
I think the mass is too high but give it a few quadrillion years it could
If that pulsar is expeling mass out of that mate star, suposing that it have an regular orbit, eventually that mate star will be sucked to the pulsar, right?
that's what I thought too... it only makes sense, right?
The lighthouses of space
Wow
i think it is possible, in a VERY contrived situation, to form a toroidal Neutron star. where several of them merge in just the right way. and just a thought... might it be possible to keep adding mass, to get a toroidal shaped black hole? and thus... would the singularity be a circle?
From what i have learned, when a black holes mass INCREASES ( which a black hole can't do by itself) it forms a oval shape.
Dexter Peterson
simulations show a weird kind of egg shape. like with hot Jupiters. but it may not be exact
Toroidal shape is gravitationally unstable
A pular binary system should reveal much about the pulsat's true nature. What if the spin of the pulsar is rapid enough for centrifugal force to counteract gravity at its surface?
If it were, it would not be able to squeeze matter on its surface to the neutron degenerate matter
So it is so dense that it actually is a Quark star and not a neutron star?
In Second Grade at Knoxville's Pleasant View Elementary when Miss Hannah was Homeroom Teacher, for Halloweening my Mother got me a Halloween Costume which I reluctanty wore: a female vampire with a black-widow spider over the mask's forehead. Even my Teacher Miss Hannah made jokes about it. After school, when a neighbor asked me to show him my Halloween costume I wouldn't show it at all but RAN AS FAST I COULD to the House as though it were a Marathon Sprint! I just didn't want anyone to know that costume!
But can it run crysis?
Could planets still exist/form in common neutron stars systems?
They can and they do. In fact the first planets ever discovered outside the solar system were found around a pulsar way back in 1992. There's a Wikipedia page on pulsar planets.
BabakoSen thank you =)
***** There's still some debate as to whether or not these planets formed from the fallback debris of the supernova or if they are the stripped-down cores of Jovian planets or brown dwarfs. What little research I've done on the subject suggests the former, but the jury's still out. Like most things in astronomy, though, if you're split between 2 plausible explanations, the reality is probably that both occur but at different frequencies.
this is good! why aren't you sharing this video on twitter?? educate the masses! ;) #true
how do we know its spinning? and what started it spinning?
Go to Google and ask both of those questions. You will get the right answers.
Rand Babs we detect them by the charged particles being ejected from the magnetic poles because of the super powerful electromagnetic field.
As for spinning, that's simply the conservation of angular momentum, like how a spinning ice skaters speed of rotation increases as they pull their arms in.
All stars spin, but if you want to know why it's spinning so fast find an astrophichist.
Burning something that is already burning. Dam cosmos, you scary.
Music...Space...Time
subtitles please!
nasa has a nice video
The thing that I want to know is: What does the core consist of? I don't think we will find it on the periodic table!
More neutrons and protons probably
yeah, I looked it up, the core is made of neutrons
@@AverageAlien prior to the collapse, the neutron star throws out metals. My question is what does the core consist of that causes it to become a black hole. Our sun will collapse into a ball of iron. I'm wondering if the core consists of an unknown element other than neutrons! As we know star cores fuse hydrogen and helium into various elements. I dare to wonder...
@@proslice56 Okay, so, neutron stars are called neutron stars because it is so dense, every proton and electron gets fused together in the core, so the core is made out of neutrons. It cannot be made of another element, or any element. Unless you mean the OG stars core
Only a minute portion of the entire universe is visible and there is a GREAT deal unseen by our galaxy blocking our view !!!!
pulsar
very giid
Looks like the formation of a Galaxy if u ask me !
Not at all
+Lillian Banda I think you need to go Troll somewhere else !!! Good bye !!!
+Rusty Fox where did you study astronomy? and what makes you think its a galaxy
I can see RIGHT NOW - yu are just ANOTHER TROLL !!!
+Rusty Fox How do you reckon its that? al the edge pf the galaxy there are clusters of gas energy and dust and also clusters of stars that generate other stars, after a neutron star collapses thats it
What would actually happen if a Black Hole would eat a Neutron Star?
Epilepsy warning for flashing light.
PEOPLE THINK WERE THE ONLY ONES.,.....
at 4:00 is he trying to seduce the viewers?
Mercede well, didn't it work?
What's the speed of an X-Ray?
+Roland Aranjo xray is light but litlle more powerfull light so speed of light
+Roland Aranjo light is an electromagnetic wave, all electromagnetic waves including X-ray travel at the same speed, which we call the speed of light.

Kolejny raz starają się wytłumaczyć coś czego nie wiedzą. Tylko zakładają, że wiedzą co to jest.
am I weird I watch anime i like gaming and i like modern physics
No, because I'm the same.
O H .
To the guy at 4:00 . Cant you speak louder and clearer. You are hurting my ears.
Pulsars are by far my favorite astronomical object.
Ok
For pity's sake turn the damned music off.
For what I understand to be a black widow spider: a small black spider with a white spot on it's back; before the old deteriorating home on 110 West Church, Wintersville, Ohio was demolished on March 13 of 2013; within the side porch that Place that was enterable with a few concrete steps leading to a bedroom door: one time, several years ago, way before 2013, when I entered that porch, a 9-pointed cardboard star that was painted yellow had been taped onto the bedroom door's upper window; right next to it on an inner wall of the porch was a fake or covered up window (this House on 110 West Church Street was built in the 1930's with the porch and bedroom added as an extension in the 1950's): on the lower pane of that window crawled a Black Widow Spider! A peculiar Harbinger and Portent?
Thank you NASA family, please, if you can give me as much Rs radiation field super computer digital simulations as you can, thank you, peace and love, Doug.

Duh! That's what all the neutron stars we know of are doing, that's how we detect them.
