Does anyone here know anything about white dwark stars?

Question

One person says they act one way and the next person says its just the opposite. Who is right about how white dwarf stars really live in the universe?

There is a spelling error here-the word should be "White Dwarf Star"

Answer 2

One of the closest white dwarfs is Sirius B, 10 light years away. You can pick it out with a small telescope. It's the faint companion of Sirius, which is one of the brightest stars in the sky. White dwarfs have masses comparable to the Sun but are only about the size of the Earth. So they're very dense. A teaspoonful would weigh about two tonnes on Earth and much more on the star, because their gravitational fields are so strong. A white dwarf will continue to shine for a long time.

Answer 3

A white dwarf the remnant of a massive star[20 solar mass]that went super nova
The white dwarf is a 2 or 3 solar mass stellar remnant about 100 km in diameter.
It shines fairly feebly and is one step up from a neutron star which contains slightly more mass but is only about 12 km in diameter..
A place to stay away from!

Answer 4

A white dwarf is a star of below average mass that has come to the end of it's life cycle and has collapsed within itself into what is called a white dwarf which shines very feebly.

Answer 5

Zee prime is incorrect. Sirius B is not visible through any commercially available telescope. The white dwarf is far too dim, and too close to Sirius to be detected through such a telescope.

Answer 6

they do not shine because of their gravity, instead they shine because they are hot, you compress that much matter into that small of a space its bound to heat up. white dwarfs will shine for a long long time before they cool down.
