Why are there no white dwarfs among the 100 brightest stars?
White dwarfs have very small surface areas compared to main sequence stars and therefore cannot emit as much light.

Yes, some of the 20 nearest stars are white dwarfs. For example, Sirius B, the companion star to Sirius A, is a white dwarf. Among the 20 brightest stars, Sirius B is the only white dwarf.

No. Stars become white dwarfs after dying.
What stars are the oldest red dwarfs white dwarfs red stars or giant stars?
The oldest stars are typically red dwarfs, which are small, cool, and faint stars that have long lifespans. White dwarfs are the remnant cores of low to medium mass stars, not the oldest. Giant stars are intermediate stage stars that have evolved away from the main sequence.
Do all stars begin as white dwarfs?
No. Stars do not start as whit dwarfs. A white dwarf is the remnant of dead star.
What do white dwarfs and neutron stars have in common?

Why are white dwarfs common?
White dwarfs are the remnants of dead low to medium mass stars, which is the mass range of the majority of stars.
Is white dwarf a star?
Many stars are white dwarfs.
Are the hottest stars the brightest?

Are white dwarfs alive or dead?
White dwarfs are stellar remnants, so it a simplified form, they are dead stars.
Where are white dwarfs supeegiants and red giants?
White Dwarfs, Supergiants, and Red Giants are stars that are found in the sky.
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.
