Compact Stars As The Endpoint of Stellar Evolution
Compact stars form the endpoint of stellar evolution. A star shines and thus loses energy. The loss from the radiating surface is compensated by the production of energy from nuclear fusion in the interior of the star. When a star has exhausted all its energy and undergoes stellar death, the gas pressure of the hot interior can no longer support the weight of the star and the star collapses to a denser state: a compact star.

Famous quotes containing the words compact, stars and/or evolution:
“What compact mean you to have with us?
Will you be pricked in number of our friends,
Or shall we on, and not depend on you?”
—William Shakespeare (1564–1616)
“Throw the children into the river; civilization has given us too
many.
It is better to die than to grow up and find that you are colored.
Pluck the stars out of the heavens. The stars mark our destiny. The
stars marked my destiny.
I am tired of civilization.”
—Fenton Johnson (1886–1958)
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
