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.
See related questions.
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.
They are usally not has bright has other stars.
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).
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
A white dwarf will start off around the brightness of it's original host star but slowly fade away as time progresses.
No they are not bright. They are very dense bodies packed very tightly so that one tea spoon weights 3 tons.
billions
It is a white dwarf.
Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.
A nova is created when additional material is accreted onto the hot surface of a white dwarf.If sufficient material is accreted that pushes the mass of the white dwarf over the Chandrasekhar limit of about 1.38 solar masses a type Ia supernova will occur.See related questions.
The outside is. The main bulk of the star is made of electron-degenerate matter.
A star on "main sequence" is a period in a stars evolution.A white dwarf is a stellar remainA supergiant star is the size of a very big star.So they are completely different and not even related.
Pluto is not a white dwarf star, it is just a dwarf planet.
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.
No, Pollux is not a white dwarf, it is a orange giant star.
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.
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.
a white dwarf star
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.
It is called white dwarf. A white dwarf is a small star. If you heard of red giant it mean huge star.
A white dwarf is much larger than a neutron star.
