WHITE DWARF
White dwarves (also known as degenerate dwarfs), are stellar remnants mainly composed of electron-degenerate matter and are white in color. The have a solar mass of up to 1.4, beyond this point, beyond this point, the pressure being exerted by the individual atoms is not able to hold back the gravitational pressure pulling it together The star would collapse down to a more compact object, like a neutron star or a black hole.. White dwarves are very dense, their average density being about one million times denser than that of the sun. A single sugar cubed amount of white dwarf would weigh approximately one tonne. Its volume comparable to that of the earth, and it’s mass comparable that of the sun. A white dwarf has a faint luminosity which comes from the emission of stored thermal energy. The nearest known white dwarf star is Sirius B, the smaller component of the Sirius binary star and is 8.6 light years away. Currently, there is thought to be 8 white dwarfs among the hundred star systems …show more content…
Eventually, the star will run out of hydrogen fuel in its core and this fusion will stop. The star will then start to collapse, but before it is able to completely collapse, a new shell of hydrogen gets going. This causes to outer layer of the star to puff out into a red giant. If a star is large enough, it will be able to begin burning helium to carbon. One this fuel runs out and this new process stops though, the star has absolutely no fuel it is able to use, so it releases its outer layers, which reveals the hot carbon core: the leftover material resulting from this last fusion reaction. The core begins out as hot, but then steadily cools over time and eventually; after billions and trillions of years, the white dwarf star will cool to the background temperature of the
