In addition to being amazingly dense, neutron stars . The magnetic fields of the stars also collapse and become very very concentrated. A white dwarf is supported by electron degeneracy pressure, a neutron star by neutron degeneracy pressure (go look those terms up for a quick physics lesson). Despite their very high densities, neutron stars are limited to between 1.1 and 3 solar masses, with the most massive observed weighing only 2.1 times as much as the Sun. Many stars in the universe are in binary systems - two stars bound by gravity and orbiting around each other (think Luke's home planet's suns in "Star Wars"). What would happen to a person standing on the surface of a neutron star? The HR diagram is an observational diagram.Whilst neutron stars could be placed in the HR diagram in the same way as white dwarf stars are, it turns out to be impractical to do so because the photospheric luminosity and photospheric temperature of neutron stars is next to impossible to determine.
