Is a white dwarf the youngest star?

Answer 1

Yes indeed. All the white ones are.

They are stars that have released nearly all the chemical energy from the hydrogen they contain in the form of heat and light

When they become too cool to radiate any heat they are called black dwarfs.

Answer 2

Depending on the original mass of the host star, a white dwarf can be as high as 150,000 degrees kelvin.

This temperature will slowly radiate into space until all internal heat has been dissipated.

This process will take billions and billions of years. So long in fact, that any white dwarf created near the beginning of the Universe is still radiating heat into space.

Answer 3

They are usally not has bright has other stars.

Answer 4

Estimates say that around 6-7% of the stars are white dwarfs.

Still, it is known that around 97% of the stars are bound to end up as white dwarfs in the future (due to their mass).

Answer 5

No.

A white dwarf is the remains of a medium sized star that has lasted for billions of years.

The youngest star is a protostar

Answer 6

A white dwarf will start off around the brightness of it's original host star but slowly fade away as time progresses.

Answer 7

No they are not bright. They are very dense bodies packed very tightly so that one tea spoon weights 3 tons.
