Black Dwarf.
No, white dwarf stars do not undergo nuclear fusion like main sequence stars, including our Sun. White dwarf stars are the remnants of low to medium mass stars, and they use stored thermal energy to shine and gradually cool over time.
A red giant has been greatly inflated by the energy from nuclear fusion in a shell around the core. In a white dwarf fusion has stopped, the core has collapsed, and the low-density outer layers have been expelled into space.
A white dwarf is not considered a "dead star." It is considered a dying star, but not dead yet. A white dwarf is at its smallest state and could become a supernova when its center runs out of fuel to burn.
It is estimated to take at least several hundred trillion years.
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.

No. A white dwarf is the remnant of a star in which fusion as stopped.
No, white dwarf stars do not undergo nuclear fusion like main sequence stars, including our Sun. White dwarf stars are the remnants of low to medium mass stars, and they use stored thermal energy to shine and gradually cool over time.
No. The energy of a white dwarf is simply residual heat.
The gas being used as a fuel source for white dwarfs is primarily hydrogen. During nuclear fusion reactions in the core of a white dwarf, hydrogen atoms are fused together to form helium, releasing energy in the process.
As a white dwarf loses energy and cools down, it eventually transitions into a black dwarf. A black dwarf is a hypothetical stellar remnant that has cooled to the point where it no longer emits heat or light. It is smaller and denser than a white dwarf.
A red giant has been greatly inflated by the energy from nuclear fusion in a shell around the core. In a white dwarf fusion has stopped, the core has collapsed, and the low-density outer layers have been expelled into space.
White dwarf stage. Note that not all stars reach this stage. Some stars experience runaway criticality and go supernova. Also, white dwarf stars in binary systems can still go nova if they are acquiring hydrogen from their partner.
Answer: A shooting star Answer: One with a small surface, such as a white dwarf or a neutron star. These are "dead stars", in the sense that energy production has stopped.
A white dwarf is the remains of a dead star, not the birth of a new one.
Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.Yes, that is correct. A white dwarf has run out of fuel - it used it up.
stars are not always white there are many different types of star for example: Black Dwarf Red Giant White Dwarf Blue Giant Neutron they are all varying colors because of the configurations of gas and energy of particals. however 97% of our galaxy's stars are the fabled white dwarf these are white because they are expelling there entire energy at once, the white dwarf is the final stage of a stars life, aside from the purely theoretical black dwarf
