what are the densest stars known to exist?
red supergiants
neutron star





















































a neutron star is the collapsed core of a giant star which before collapse had a total mass of between 10 and 29 solar masses. neutron stars are the smallest and densest stars, not counting black holes, hypothetical white holes, quark stars and strange stars. neutron stars have a radius on the order of and a mass of about 1.4 solar masses. they result from the supernova explosion of a massive star, combined with gravitational collapse, that compresses the core past white dwarf star density to that of atomic nuclei.

lss 4067 has an absolute bolometric magnitude of −11.4, making it one of the most luminous stars known. indeed, many of the hottest and most luminous stars known are o-type supergiants, or wolf-rayet stars. lss 4067 has an unusual spectrum, with various emission lines including n iii and he ii emission lines, thus the "f" in its spectral type. because of this unusual spectrum, classifying the star or deducing its properties has proved relatively difficult: for example, the effective temperature is predicted to be too cool and the surface gravity too high.
