what is a star with a contracted burned out center called?

Answer 1

The burned out centre of a low mass star is a white dwarf. It's a hot ball of carbon and oxygen, though too cool for thermonuclear reactions to occur. They're about the size of Earth and are too dim to be seen with the naked eye.

Answer 2

When a low- to medium-mass star exhausts the nuclear fuel in its core, it collapses under the gravitational pressure of its own weight into an extremely compact, dense star known as a white dwarf. As a more massive star (6 to 8 solar masses) collapses to a white dwarf, it blows off more than half of its outer layer into space as a planetary nebula--gas and dust that may provide building material for planets in newly forming solar systems. Although dimmer than the original star, a white dwarf will continue radiating light for several billion years from thermal energy (heat energy) trapped in its interior.
As a white dwarf slowly loses energy and cools, it changes color from blue-white, to white, to yellow, to orange, and finally to dull red. After several billion years, the white dwarf exhausts its energy supply, and becomes what is known as a black dwarf.

Answer 3

White dwarfs are the cores left over from normal stars (like the sun) that have died. Neutron stars and black holes are the leftover cores of extremely massive stars that have died.

Answer 4

But Tom Cruise knows the history of Astronomy and you don't.

Answer 5

black dwarf, neutron star, or black hole?

however, could also be called tom cruise.
