Chandra also finds regions aglow with the light of massive young stars. The connected arrow goes to the left because their X-ray luminosities could be 2x10^30 erg/s or lower). I like that you included the actual masses at which stars will become either a white dwarf, neutron star, or black hole. It finds a sea of hot gas enveloping thousands of white dwarfs, neutron stars and black holes. We look at the skies and see stars at various stages of their evolution — young ones, middle aged ones, supernovas, and the remnants of supernovas — white dwarves, neutron stars, black holes. Royal Astronomical Society that suggest that two “compact stellar remnants” — which could be neutron stars, black holes or white dwarfs — collided and merged, resulting in a short-duration gamma-ray burst that hit Earth. Brown Dwarfs, in theory, have been around awhile, but the first to be discovered came in 1995. For those with serious interest in neutron stars and other compact objects, an excellent reference is "Black Holes, White Dwarfs, and Neutron Stars", by Stuart Shapiro and Saul Teukolsky (1983, John Wiley and Sons). I definitely needed a refresher on star life cycles since I took Intro Astronomy a few years ago. Brown Dwarfs, is a fourth, remnant of a dead star after White Dwarfs, Neutron Stars, and Black Holes.
