What is the gravity of a white dwarf?

Main-sequence stars form from clouds of dust and gas drawn together by gravity. How the stars evolve through their lifetime depends on their mass. The most massive stars, with eight times the mass of the sun or more, will never become white dwarfs. read more

It's a white dwarf that has about the mass of the Sun and about the radius of the Earth (6400 km): actually it is said to be a bit smaller than the Earth at 5540 km, which increases its surface gravity by a factor of the square of the ratio of the radii. read more

With a surface gravity of 100,000 times that of Earth, the atmosphere of a white dwarf is very strange. The heavier atoms in its atmosphere sink, and the lighter ones remain at the surface. Some white dwarfs have almost pure hydrogen or helium atmospheres, the lightest of elements. read more

Because the white dwarf is supported against gravity by quantum degeneracy pressure instead of by thermal pressure, adding heat to the star's interior increases its temperature but not its pressure, so the white dwarf does not expand and cool in response. read more
