There is no source of energy heating a white dwarf. The heat is left over from when it was a full-fledged star, like a stone pulled from the coals of a fire. The white dwarf glows simply because it is very hot.

How are the sun and a red dwarf similar?
Both the sun and a red dwarf are main sequence stars that produce heat and light by fusing hydrogen in their core and turning it into helium.
What does the color of a star help to determine about the star?
The color of a star determines the heat of the star. For example; a white dwarf star does not produce nearly as much heat as our sun does. However, one day, our sun will turn into a white dwarf star. When this happens there will not be enough heat to live on Earth.
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 does a white dwarf die?
When it has radiated all of it's heat back into space. It then becomes a black dwarf.
What would happen if a white dwarf collided with the sun?
In one way, yes. If the white dwarf is in a close binary system with another star, when that star expands into a red giant, the white dwarf can start siphoning gas from it. Eventually the heat and pressure of the accumulated gas ignites nuclear fusion, triggering a Type 1a supernova.

Can a white dwarf that has no fuel make its own energy?
No. The energy of a white dwarf is simply residual heat.
Why is a star to be dead when it becomes a white dwarf?
At that stage, it will no longer produce energy. All the energy it radiates out is its residual heat, and it will gradually get colder and colder. Due to its small size and high density, however, it will take trillions of years for the white dwarf to become a black dwarf.

When a white dwarf loses all of its heat and cools down it become a?
black dwarf
What gas is being used as a fuel source for the white dwarf?
There is no fuel for a white dwarf. A white dwarf is a remnant of a star in which fusion has stopped. There is, however, quite a bit of leftover heat, so the white dwarf still glows.
How filipino produce heat and light?
Filipino is an inhabitant of the Philippines , and they produce heat through body heat , they dont produce light :S

Does a light bulb produce light?
they produce protons and electrons they are collition then the light produce and heat produce
Does light produce heat?
Heat can not produce light without heating a certain object or material meaning heat by itself cannot produce light on its own.
When does a white dwarf die?
When it has radiated all of it's heat back into space. It then becomes a black dwarf.
