What is the life expectancy for alphs centauri b?
Alpha Centauri B is a star, not a planet, and it has a life expectancy of approximately 10 billion years. As a member of the Alpha Centauri star system, it is a bit older than our Sun, which has an estimated life expectancy of about 10 billion years as well. However, Alpha Centauri B is expected to have a stable lifespan, continuing to shine for several billion more years before eventually evolving into a red giant and then a white 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.
Which type of star is NOT undergoing nuclear fusion?
A protostar; also a brown dwarf.
Does a star change during its life cylcle?
Yes, a star undergoes significant changes throughout its life cycle. It is born from a collapsing cloud of gas and dust, transforms through nuclear fusion, and eventually dies, either collapsing into a dense core (like a white dwarf or neutron star) or exploding in a supernova. Each stage brings about different characteristics and behaviors in the star.
Which type of star has the longest life span?
A red dwarf.
How long is the Sun's life expectancy?
It should "live" for about 5 billion years as it is, more or less. Then it will become a red giant star. Then it becomes a white dwarf. Finally it will "die" as a 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.
Steps in the life of a star?
the steps in the life of a star is the yellow dwarf,red giant,white dwarf & the black dwarf.
What is a death star?
The death star is known as the nemesis star AKA the death star, brown dwarf star, red dwarf star, or the sun's twin.
What is a small brown star called?
That's called a brown dwarf.
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.
Is a brown dwarf bigger than the sun?
No Brown Dwarfs are too small to be considerred a star.
Star of life?
Nebule > Star > Red Giant > Red Dwarf > White Dwarf > Supernova > Neutron Star > Black Hole.
What star is smaller than the sun?
A brown dwarf would qualify.
A brown dwarf is what's left when a large star explodes true or false?
False. A brown dwarf is a failed star that cannot sustain nuclear fusion. When a star explodes it will leav behind either a neutron star or a black hole depending on its mass.
What is the difference between a brown dwarf and a protostar?
A protostar is a star the is developing as is on the way to starting nuclear fusion. A brown dwarf is a failed star, one that failed to gather enough mass to start fusion.
How are brown dwarfs different from other stars?
A brown dwarf is a "failed star" - one that never became hot enough (not enough mass) to start nuclear fusion.A brown dwarf is a "failed star" - one that never became hot enough (not enough mass) to start nuclear fusion.A brown dwarf is a "failed star" - one that never became hot enough (not enough mass) to start nuclear fusion.A brown dwarf is a "failed star" - one that never became hot enough (not enough mass) to start nuclear fusion.
