An object below a certain mass will never become a star in the first place; rather, it will remain a brown dwarf. And an object above a certain mass will have such a strong gravitation (once its fuel runs out) that it will collapse into a neutron star, instead of a white dwarf.

Why do all white dwarfs have about the same mass?
All white dwarfs do not have about the same mass. White dwarfs vary in mass because the stars they form from are not all the same mass.
What is a small hot star that is near the end of its life called?
There are small hot stars - White dwarfs, neutron stars but by furtue that they are hot, means they are not near the end of their lives. It takes a long long time for all the residual heat to escape into the Universe. So, there are NO hot stars near the end of it's life.
Does a white dwarf star use hydrogen for energy?
No. A white dwarf is the remnant of a star in which fusion has stopped. There is no hydrogen left. All the energy left in a white dwarf is residual heat.
Describe in general the life history of a star with an average mass like the Sun?
A star, the size of our sun, does not explode into a supernova. Instead, toward the end of its life, it grows over 1000 times its size into what is called a Red Giant. After that it implodes and looses mass at a quick rate reaching the white dwarf stage. After that it is a black dwarf and looses all its energy and mass.
What is a white and red dwarf star?
A White Dwarf star starts as a small to intermediate size star, like our Sun is currently. That eventually becomes a red giant star. Eventually that blows off everything but the hot very dense core of "electron degenerate matter". What is left is a hot ball of mainly carbon and oxygen that will eventually cool and dim and turn into a black dwarf star. A white dwarf has a second chance of life and death in a close binary star system, where the white dwarf draws mass from the companion star. Once the mass of the white dwarf reaches the Chandrasekhar limit of approximately 1.38 solar masses or roughly 140% of the mass of our Sun, the core can no longer hold the gravitational pressure and a Type 1a Supernova may occur. A Red Dwarf star is a " Main Sequence " star, but with very low mass and luminosity. You need a telescope to see one. However, they make up about 80% of all stars and they have very long lifetimes.
Why do all white dwarfs have about the same mass?
All white dwarfs do not have about the same mass. White dwarfs vary in mass because the stars they form from are not all the same mass.
What is the next stage in the life of a lower-mass main-sequence star?
white dwarf. unless you count black dwarf of which none have been observed, only theorized.
What is a small hot star that is near the end of its life called?
There are small hot stars - White dwarfs, neutron stars but by furtue that they are hot, means they are not near the end of their lives. It takes a long long time for all the residual heat to escape into the Universe. So, there are NO hot stars near the end of it's life.
Can a female Robo Dwarf Hamster mate with a male winter white dwarf hamster?
No, they cannot because all hamsters have to be the same breed to mate.
What is the last stage in the life cycle of earth's sun?
The core will be known as a white dwarf, while the outer regions will be known as a planetary nebula.In the end of the life cycle of the Sun, the white dwarf will release all of its remaining heat and will evolve into a cold dark mass known as a black dwarf.
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.
What keeps white dwarf from collapsing under its own weight?
A white dwarf star, as well as any other stable variety of star,is held together by the pressure popularly known as "gravity".In the opposite direction, white dwarf stars are kept from collapsing completely by degeneracy pressure. Specifically, for white dwarf stars, it's electron degeneracy pressure, which arises from the fact that electrons are fermions and cannot all occupy the same energy state. For higher mass stars, the force of gravity is able to overcome this and push all the electrons into the ground state, and the star is supported by a different kind of degeneracy ... neutron degeneracy, which is the same thing but with neutrons ... and you get a neutron star. At even higher masses, even that isn't sufficient and the star collapses all the way into a black hole.
Does a white dwarf star use hydrogen for energy?
No. A white dwarf is the remnant of a star in which fusion has stopped. There is no hydrogen left. All the energy left in a white dwarf is residual heat.

When a white dwarf loses all of its heat and cools down it become a?
black dwarf
What happens to stars which are less massive than sun?
Stars with more than about 80% of the Sun's mass behave like the Sun. They should eventually become red giant stars then white dwarf stars. Stars with mass of between about 8% and 80% of the Sun's mass are red dwarf stars. Below that come the "brown dwarfs, which aren't really true stars at all. The red dwarfs cannot fuse helium, so they simply become "white dwarf" stars when they have used up all their hydrogen "fuel".
Why do some stars die out as neutron stars while others die out as black holes and white dwarfs?
It won't turn direclty into a black dwarf. Some stars will turn into a white dwarf; when the white dwarf cools down (it no longer produces energy), it will become a black dwarf. It is not likely that there are black dwarves yet, since the Universe isn't old enough; this is an expected future stage in the development of some stars. and be cause yolo
