Black holes, white dwarfs, and neutron stars Saul A. Teukolsky, Stuart L. Shapiro

These are produced by normal stars feeding material onto the compact, dense remains of stars that have reached the end of their evolutionary trail – white dwarfs, neutron stars and black holes. We review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Short duration gamma-ray bursts are thought to be caused by the merger of some combination of white dwarfs, neutron stars or black holes. If it is more massive than that about 8 solar masses the star will go supernova and leave behind a neutron star, or if massive enough a black hole. The RXTE had an observatory mission, using X-ray wavelength emissions to study the environment around white dwarfs, neutron stars, and black holes. Stars all begin life the same way but the end of the life cycle of a star is the interesting part. In many binary star systems, the primary star is a compact object such as a black hole, a neutron star, or white dwarf. The combined pressure of the electrons holds up the white dwarf, preventing further collapse towards an even stranger entity like a neutron star or black hole. Black holes, white dwarfs, neutron stars and quasars emit an extremely strong, pulsing beam of Light, which is made up of the spectrum of Light waves that include Ultra-Violet. €�White dwarf/neutron star or black hole binaries are thought to be quite rare, although there is a huge range in the number per Milky Way-like galaxy in the literature. Depending on many different variables a star can end up as a white dwarf, neutron star, or a black hole. In addition, many binary systems can have compact components and can exist in a variety of ways. An artist's impression of the merger of two neutron stars. 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. Now, researchers think they've got the solution — the burst of radiation could have been emitted by merger between superdense objects like black holes, white dwarfs or neutron stars.
