2.65. It has a white dwarf companion of about 13
This star would be a white dwarf, as it has a high surface temperature of 20000 K but a low absolute magnitude of 10. White dwarfs are small, dense remnants of low to medium mass stars that have exhausted their nuclear fuel and collapsed.
white dwarf star
Yes, far smaller. A red dwarf is a whole star in and of itself. A white dwarf is the collapsed remnant of the core of a low-to medium mass star. A white dwarf may be about the size of Earth.
That is a difference of ten magitudes so the factor in brightness is 10,000.
Depends on the white dwarf in question. They can have a myriad of absolute magnitude values.

Sirius B is a faint white dwarf companion of Sirius A It has an apparent magnitude of +8.3 and an absolute magnitude of +11.18

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 in the life cycle of a star, a white dwarf can cool and become a black dwarf
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 a white dwarf is a small compact star.
That might be a white dwarf.
No. A white dwarf is a remnant of a dead star.
