A white dwarf (or degenerative star) is the stellar remains of a star, that is composed mostly of electron degenerate matter. The electrons are already at the lowest possible energy level.
A white dwarf's mass is comparable to that of the Sun but its volume is comparable to that of the Earth.
White dwarfs are so dense because they are the remnants of high-mass stars that have exhausted their nuclear fuel and collapsed under their own gravity. The electrons in white dwarfs are degenerate, meaning they resist further compression, leading to a compact and dense state.

Why are white dwarfs so heavy?
White dwarfs are heavy because they are the remnants of massive stars that have exhausted their nuclear fuel and undergone gravitational collapse. They are incredibly dense, packing a mass similar to that of the Sun into a much smaller volume. This high density is a result of electron degeneracy pressure balancing the gravitational force pulling inwards.
What is the classification for small and hot stars?
Small and hot stars are typically classified as white dwarfs. These stars are the end stage of evolution for stars with low to medium mass, such as the Sun, and are characterized by their high temperature and small size. White dwarfs are very dense and can appear white in color due to their high surface temperature.
Do stars die out after becoming white dwarfs?
No. Stars become white dwarfs after dying.
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 it called when a bunch of white dwarfs explode?
There is no such thing as a "bunch of White dwarfs", let alone exploding white dwarfs. The nearest explanation would be a nova. See related question.
What do white dwarfs and neutron stars have in common?
Both white dwarfs and neutron stars are extremely dense remnants of the collapsed cores of dead stars.

Are white dwarfs alive or dead?
White dwarfs are stellar remnants, so it a simplified form, they are dead stars.
Does a white dwarf have a event horizon?
No, white dwarfs do not have an event horizon. Event horizons are a characteristic feature of black holes, where the gravitational pull is so strong that not even light can escape. White dwarfs are dense stellar remnants, but they do not have the extreme gravity needed to form an event horizon.
Are white dwarfs one of the densest forms of matter?
Yes, white dwarfs are one of the densest forms of matter in the universe. They are incredibly compact and have densities that can be hundreds of thousands of times greater than that of Earth. This high density is a result of the immense gravitational forces acting on the star's core.
How are white dwarfs so bright?
Actually they are fairly dim.
What occupationdo the Dwarfs in Snow White have?
Did Snow White ever had sex with the dwarfs
Where did Snow White find her dwarfs?
Well for a start snow white didn't find the dwarfs they found her sleeping in the Grumpy's bed so Grumpy was very Grumpy
What is a small hot very dense star?
Both white dwarfs and neutron stars match the description. Neutron stars are smaller, hotter, and denser.
Who were the dwarfs in Cinderella?
there were no dwarfs in Cinderella, only mice. there are dwarfs in snow white
