What will the Sun end up as when its nuclear energy source dies out forever?
The Sun will eventually end up as a white dwarf, a dense, Earth-sized remnant of a star. This will happen after it exhausts its nuclear fuel and sheds its outer layers into space, forming a planetary nebula.
What happens to the size of a white dwarf when its mass is increased?
When the mass of a white dwarf increases, its size decreases. This is because the increased mass causes the white dwarf to contract under its own gravity, making it smaller and denser.
What is the upper limit to the mass of a white dwarf?
The upper limit to the mass of a white dwarf is about 1.4 times the mass of the Sun, known as the Chandrasekhar limit. Beyond this point, the white dwarf may collapse and explode in a supernova event.
Is a white dwarf star is one that does not have fuel to make is own energy?
That's called a "black dwarf". Such objects are hypothetical; they are not expected to exist yet, since it takes a white dwarf longer, to cool down to a black dwarf, than the current age of the Universe.
How long will the sun be a red giant before it transitions into a white dwarf?
The sun will be a red giant for about 1 billion years before transitioning into a white dwarf.
When did Dwarf Fortress happen?
Dwarf Fortress happened in 2006.
Are dwarf stars black holes?
no, dwarf stars don't have enough mass
Can only giant stars become black holes?
The basic requisite is that enough mass gets together. This can happen with a large star if, after it explodes as a supernova, enough residual mass remains to go beyond the limit of a white dwarf, and of a neutron star. Yet there is also another possibility: a star may end up first as a white dwarf or as a neutron star, but it may eventually receive enough infalling matter to become a black hole.The basic requisite is that enough mass gets together.

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.
Can a dwarf planet become a moon?
Yes, a dwarf planet can become a moon if it is captured by the gravitational field of a larger planet. This process can happen when a dwarf planet gets close enough to a planet and is pulled in by its gravity. Once captured, the dwarf planet would then orbit the larger planet as one of its moons.
How does a brown dwarf compare to our sun?
The distinguishing feature is that a brown dwarf gets hot enough to fuse deuterium (hydrogen-2), but not hot enough to fuse hydrogen-1.
Is a dead star the some as a black dwarf?
No, a dead star is different from a black dwarf. A black dwarf is a type of stellar remnant, but not all stars become black dwarfs. When a star dies it will leave behind a white dwarf, a neutron star, or a black dwarf as a remnant depending on its mass. Given enough time a white dwarf will eventually cool to a black dwarf. The universe is not old enough for this cooling to have happened yet.
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.
Are there any black dwarf stars?
No. It is estimated that it would take trillions of years for a white dwarf to cool to a black dwarf. The universe is not old enough for that to have happened yet.
What would happen if a dwarf star crashed into a planet?
If a dwarf star crashed into a planet,the planet would likely explode.
What happens when a dwarf bean plant does not have enough light?
it will not bloom.
Are dwarf planets round?
Yes. While not considered planets, dwarf planets are still massive enough to be rounded by their gravity.
