White dwarf stars are not luminous because of their small sizes, they are not able to radiate a lot of light at once.
No. A dwarf star is a small star. A white dwarf is just one particular type of dwarf star, but there are other types.
No a white dwarf is a small compact star.
A white dwarf is a small, dense star that forms after a medium-sized star exhausts its nuclear fuel and sheds its outer layers. It is mainly composed of electron-degenerate matter, and its size is comparable to that of Earth, even though it can have a mass similar to that of the Sun.
A cooled white dwarf is a black dwarf. I think you are thinking of a neutron star which has nothing to do with a white dwarf.
No Rigel is a huge, blue supergiant of spectral class B8 Ia, Rigel has an intrinsic brightness about 40,000 times as luminous as that of the sun.
A white dwarf could not become a red dwarf. A white dwarf is a remnant of a dead star. A red dwarf is a star with a very low mass.
No. A white dwarf is the remnant of a low to medium mass star.
No, Rigel is not a white dwarf. Rigel is a blue supergiant star located in the constellation Orion. White dwarfs are the remnants of small to medium-sized stars that have exhausted their nuclear fuel and collapsed.
A white dwarf star's temperature can range from approximately 7000K to 19000K.
No, a typical white dwarf star is roughly the size of the Earth.
A white dwarf is much larger than a neutron star.
A white dwarf is the remnant of a low to medium mass star.
