Is Jupiter a brown dwarf?
No. Jupiter is a gas planet. It is not massive enough to be considered a brown dwarf.
Will the sun become a brown dwarf?
No. A brown dwarf is a failed star, one that is not massive enough to start nuclear fusion. The sun is well above the threshold of fusion. When it dies it will become a white dwarf.
What is a brown dwarf's temperature?
The coolest brown dwarf so far discovered has a temperature as low as 500 -> 600 Kelvin and have a spectral class of T9
Why doesnt a Brown Dwarf become a real star?
A brown dwarf is not massive enough to create the heat and pressure at its core needed for nuclear fusion.
What is the fate of an isolated brown dwarf?
The fate of an isolated brown dwarf depends on its mass. If the brown dwarf is below a certain threshold (about 13 times the mass of Jupiter), it will cool and fade over time, eventually becoming a cold, dark object called a "rogue planet." If the brown dwarf is more massive, it may undergo fusion reactions and become a star, though this is rare for isolated brown dwarfs.
What is a possible outcome for a protostar that does no have enough material?
A brown dwarf.A brown dwarf.A brown dwarf.A brown dwarf.
How long will it take for a brown dwarf to become a black dwarf?
A brown dwarf will never become a black dwarf. A black dwarf is what becomes of a white dwarf. This process takes hundreds of trillions of years.
Is Jupiter a brown dwarf?
No. Jupiter is a gas planet. It is not massive enough to be considered a brown dwarf.
What does a white dwarf become when it gets colder?
A brown/black dwarf.
Is a brown dwarf star on its way to becoming a black dwarf?
No. A brown dwarf is a star that has too low a mass to start nuclear fusion. A black dwarf is a former white dwarf, the remnant of a low to medium mass star that ran out of fuel in its core.
What is a small brown star called?
That's called a brown dwarf.
Are brown dwarf stars young or old?
They can be any age. A brown dwarf is a failed star, one that is not massive enough to start nuclear fusion. A brown dwarf may have formed recently, or could be almost as old as the universe itself.
Can a star be a brown dwarf?
Yes, a brown dwarf is a star that failed to ignite hydrogen fusion because it did not have enough mass for a strong enough gravitational collapse. Brown dwarf stars glow dimly with residual heat for a very short time.
Will the sun become a brown dwarf?
No. A brown dwarf is a failed star, one that is not massive enough to start nuclear fusion. The sun is well above the threshold of fusion. When it dies it will become a white dwarf.
What is a brown dwarf's temperature?
The coolest brown dwarf so far discovered has a temperature as low as 500 -> 600 Kelvin and have a spectral class of T9
Why doesnt a Brown Dwarf become a real star?
A brown dwarf is not massive enough to create the heat and pressure at its core needed for nuclear fusion.
What is a small star that only gives of faint light and are cool?
That can either be an old white dwarf, a red dwarf. or a brown dwarf.
