No. Stars do not start as whit dwarfs. A white dwarf is the remnant of dead star.
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.
Yes, all those types of stars have left the main sequence.
There are two kinds of "dead" stars. One, called "brown dwarfs," even though they're actually dull red, are "dead" through not being able to fuse hydrogen into helium. They generate heat through their gravity, as Jupiter does. The other kind are the remnants of supernovae, which include white dwarfs, neutron stars and black holes. The first two of these aren't dead in the same sense as brown dwarfs, since they still radiate from fusion. Black holes and dead (except for gravity) because the matter at their hearts has become so compressed, it's been "pulled out of the universe" an occupies no space at all.
The Sun is the name of the STAR we cling to. All STARS are infernos.
Well, let me tell you, it's truly fascinating! White dwarfs are actually much smaller and cooler than supergiants, so they seem dimmer to our eyes. But despite their dimness, aren't they still shimmering orbs of beauty in the vast cosmos? Just remember, every star has its own brilliance and charm.

I think white dwarfs. This is because they are much more low mass than black holes. White dwarfs are much more common in the universe than black holes, because we have only discovered a few black holes whereas we are aware of many white dwarfs.
Somewhat confusingly, there are no "medium" stars. Stars are either dwarfs or giants. Dwarf stars (class V) come in all types: O, B, A, F, G, K, and M. There are also class VII "white dwarfs", probably better called "degenerate dwarfs" which are distinct from AV stars. In the first place, they really are small (about the size of Earth); the smallest red dwarfs are much larger, and even the so-called "brown dwarfs" are around the size of Jupiter (though much more massive). Also, they're not part of the main sequence.
True. Brown dwarfs, white dwarfs, and neutron stars are all supported against collapse by degeneracy pressure, which is a quantum mechanical effect that arises when particles are packed densely together and cannot occupy the same quantum state. This pressure prevents further gravitational collapse and supports the star against its own gravity.

Oh, dude, dead stars are like the goths of the universe - they're called "white dwarfs." They're basically the retired rockstars of the cosmos, just chilling out after burning through all their fuel. So, yeah, white dwarfs - they're like the cosmic retirement homes for stars.
some facts about white dwarfs that obviously they do not exsist becasue theyre * dwarfs * oh k ? lolz . & they are white ._. thats all bye !
Stars with more than about 80% of the Sun's mass behave like the Sun. They should eventually become red giant stars then white dwarf stars. Stars with mass of between about 8% and 80% of the Sun's mass are red dwarf stars. Below that come the "brown dwarfs, which aren't really true stars at all. The red dwarfs cannot fuse helium, so they simply become "white dwarf" stars when they have used up all their hydrogen "fuel".
Yes, stars are typically much larger than Earth. Stars range in size from small, dim stars called red dwarfs to massive, bright stars like supergiants. Even the smallest stars are still much larger than Earth.
There are lots of white dwarfs; all the galaxies have them, including ours (the Milky Way).
The Milky Way galaxy contains a variety of stars, including main sequence stars (like our Sun), giants, supergiants, white dwarfs, and neutron stars. The most common stars are red dwarfs, making up about 70-80% of all stars in the Milky Way. There are also many other types of stars, such as yellow dwarfs (like our Sun), blue giants, and red giants.
Yes. All white dwarfs are orders of magnitude farther away than Pluto is.
