- In our local galactic neighbourhood, lying 3rd closest to the earth is Luhman 16, this is a binary brown dwarf system. This star system consists of two brown dwarf stars. Luhman 16A is a L class brown dwarf. It would glow faintly red to our eyes. Studies have suggested that Luhman 16A has large bands similar to a gas giant planet.
Luhman 16B is a T class brown dwarf. This would glow faintly pink or purple to our eyes. These brown dwarfs orbit their common centre of mass with a distance of roughly 3.5 astronomical units

I've always found Brown Dwarfs to be fascinating. Great video!
I like your presentations. No long intros with basic facts endlessly repeated, IMO. You get to the point, bringing unusual and current information. I gained some very good, new insights today by watching this video and I've been following the lastest astronomy news for decades. So congratulations. IMO, you are an inovator and deserve more viewership and success. (just an opinion from a noboby.)
its cool how they actually look like a middle thing between stars & big planets
Fascinating! I'm pretty sure very few people know about these neighbors of us.
That it might appear magenta, a color that doesn't actually exist as a singular color, seems interesting but unlikely.
very interesting and easy to understand
Thank you, I'm glad you enjoyed it.
great video mate, keep up the good work
It's really fascinating to think we are just starting to really expand our understanding of space
Yes it is amazing how much we have learned in such a short space of time, and even that we are just scratching the surface.
Any planet nearby would get the same "keep warm" treatment as my burger while waiting for the fries to cook in a fast food restaurant? Under the red lights?
it was pefect thanks

Thank you, I'm glad you enjoyed it.
This could potentially change our understanding of gas giants?
M types are Stars that fuse Hydrogen (aka not a brown dwarf)

Do you have the texture of luhman A and the pink/red luhman B? I want them, if possible.
I do have the textures, but before I make them available I have 2 questions. Do you plan to use them in a video? If so credit would be nice. I'm more than happy to help out other creators. Secondly, are you familiar with Blender? If not then the materials wouldn't be of much use to you.
@@LearningCurveScience I know how to use blender. It isn't being used for a video. I'm using the textures to recreate the solar system and nearby ones in a mod for the video game "Outer Wilds". Credit can be given.
Apologies, I've been very busy with my proper job recently. Hope you liked it
@@LearningCurveScience It works. Thank you very much!
what software do you use to navigate through space like that?
I make all my videos using Blender. I do all the modelling and animation myself.
So wait luhman 16A is saturn sized
And luhman 16B is same size as jupiter?
It's a little bigger than Saturn, but yes it would appear to be, I think I worked it out at about 122,000 km for Luhman 16A (ish)
I Love your video :)
Thank you very much. That's very nice of you to say.
I don't understand why you have less subscribers ?💔
Thank you. I just enjoy making videos, and if people enjoy watching them, then that's a lovely bonus.
If a red star can fuse hydrogen into deuterium isotopes, what kind of chemical creations are happening in Jupiter's atmosphere? Sure, there is stratification of denser/lighter elements, but the volatility of the planet's winds must stir up some fancy chemical solutions, I'd think.
Whatever is happening within Jupiter… it isn’t fusion.
Has any telescope ever gotten a disk on a star, any star? All these images of a brown dwarf are completely imaginary. In any telescope it's just a point of light.

m type stars are red dwarfs not brown dwarfs and they die unlike brown dwarfs and their mass is from 80 jupiters to half the mass of our amazing sun
Each stellar class has a number of subdivisions. You are quite right that red dwarf stars are class M, but the hottest brown dwarfs are also class M but a different sub-group. I hope that clears it up for you.
Sit down teacher is speaking!

Brown Dwarfs are not True Stars
Interesting, they share some features with stars (nuclear fusion) and are classified with stars, but there are some differences. They get dimmer with age and lose the ability to fuse deuterium. I find them fascinating because until relatively recently we didn't even know they existed.
@@LearningCurveScience They are called Failed Stars. They started out red hot soon cool down over time. They share a lot feature with Gas Giants like Jupiter and Saturn. Brown Dwarf between Gas Giant and Red Dwarf Stars. I love Brown Dwarf.
stars are electric and get thier power from briland currents that connect the universe to itself pos and neg attractrion and replusion gas and dust is all you need to make and describe our universe
