Basic introduction To White Dwarfs
Heat changes the color of white
dwarfs and they can be found blue, yellow, white and even red.
A white dwarf is no longer buring but is still realeasing heat.
Eventually white dwarfs will fade away.
You can not see any white dwarfs from Earth with out a telescope.
An average white dwarf will have the mass of the Sun but it would be
the size of the Earth.
A white dwarf that is comparable to the Earth in size has a density
around 1,000,000,000 kg/m3
The density of a white dwarf is so great that a teaspoon full would
weigh about one metric ton.
White Dwarfs emitt soft x-rays. THese x-rays allow astronomers to
study the atmosphere of white dwarfs.
The thin atmospheres of white dwarfs are almost completely made of pure
helium or pure hydrogen.
Surface gravity of a white dwarf is 100,000 times that of gravity on
the Earth.
