Comparison of degeneracy conditions for a solar-type star like the Sun and for Sirius B.

The mass-volume relation for white dwarf

The mass limit supported by degenerate gas pressure: the Chandrasekhar limit

The cooling timescale of white dwarfs

Neutron stars: when the core exceeds the Chandrasekhar limit

The mass-volume relation for neutron stars

Description of the conditions in the interior of these stars. Large uncertainties due to lack of conditions to reproduce physical conditions at the interior of such dense stars.

High rotating neutron stars: Pulsars

Black-holes: when neutron stars exceed the Chandrasekhar limit for neutron degeneracy pressure.
