Here are some
words to remember:
dwarf: This is a star that is held up by
the pressure of its electrons. Due to the Pauli
exclusion principle, the electrons can not all
have zero momentum, and must therefore exert
limit: Stars with masses above this
limit will overcome the electron pressure and
collapse. The limit is 1.4 solar masses.
Stars which are significantly above the
Chandrasekhar limit may bounce just after they
collapse. This blows the surface of the star into
space and releases an enormous amount, ~ 1046
J, of energy.
star: This is a star which has
collapsed, but is held up by the pressure of
compressing the neutrons to nuclear matter
densities. The protons and electrons in a normal
star have converted via the reaction .
hole: This is formed by a star which is
so massive that it collapses to a singularity.
Even light is trapped in the interior.
