Can a white dwarf become a black hole?

No chance of a black hole. A White Dwarf is a star whose mass was insufficient to collapse to form a black hole at the end of its life when fusion ceases. The electrons with the nucleus would collapse but not to the extent that electrons would combine with protons to form neutrons.

How does a white dwarf turn into a black hole?

The most massive stars, with eight times the mass of the sun or more, will never become white dwarfs. Instead, at the end of their lives, white dwarfs will explode in a violent supernova, leaving behind a neutron star or black hole.

What prevents a white dwarf from collapsing to a black hole?

The fact that electrons are fermions is what keeps white dwarf stars from collapsing under their own gravity; the fact that neutrons are fermions prevents neutron stars from collapsing further.

What happens when a white dwarf meets a black hole?

Specifically, if the white dwarf passes close to a black hole, then it experiences simultaneous, intense stretching and compression, caused by the overwhelming tidal force from the black hole.

Are black dwarfs hot?

The ultimate stage of stellar evolution for many stars is a black dwarf. Because they emit no heat or light, these objects would be a challenge to detect if they existed today. … But the white dwarf remains hot for some time, much like a stove burner still emits heat even when it has been turned off.

Is a white dwarf hotter than the Sun?

A typical white dwarf has a carbon and oxygen mass similar to the Sun, but is much smaller in size (similar to the Earth). It is much hotter (25,000 K), but because of its small size its luminosity is low.

Why does a white dwarf not collapse?

The Nature of White Dwarfs It doesn't collapse forever because a new force develops which can resist gravity. This force is electron pressure. The material in a white dwarf has been compressed so much by gravity that all the electrons have been stripped away from all of the atomic nuclei.

Will our Sun ever explode as a nova?

The Sun as a red giant will then… go supernova? Actually, no—it doesn't have enough mass to explode. Instead, it will lose its outer layers and condense into a white dwarf star about the same size as our planet is now. … When the Sun leaves behind a nebulae it will no longer be in the Milky Way.

Can a black hole eat a white dwarf?

When a red giant first snuck too close, the black hole snatched away all its hydrogen, leaving just the core white dwarf behind. … The black hole will eat it more and more slowly, but never stop," King said.
