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

Depending on many different variables a star can end up as a white dwarf, neutron star, or a black hole. A star undergoes many radical changes throughout its lifespan including the inevitable exhaustion of its fuel source. Such is the case of 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. So far these signals were detected only in supermassive black holes, which contain millions of solar masses and is located in the center of a galaxy. Though, it is only a simulation, nothing more. Sources of gravitational waves could possibly include binary star systems composed of white dwarfs, neutron stars, or black holes. In the case of compact objects such as white dwarfs, neutron stars, and black holes, the gas in the inner regions becomes so hot that it will emit vast amounts of radiation (mainly X-rays), which may be detected by telescopes. Michael Muno is an astrophysicist who uses Chandra, among other telescopes, to study some of the most exotic objects in the Universe: white dwarfs, neutron stars, and black holes. 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. Lectures will be presented by leading Physicists and Astrophysicists working in the interface of Nuclear Physics, White Dwarfs, Neutron Star Physics and Black Holes Physics. An exhausted star will evolve into a neutron star, a black hole or a white dwarf – depending on its mass. White dwarfs are the hot, dense leftover cores of ex-stars. Therefore, it is an ideal technique to study the galactic population of faint or dark objects, such as brown dwarfs, red dwarfs, white dwarfs, neutron stars, black holes and exoplanets. We can't hope to create extremely strong gravity in the lab, so we need to look outwards into space for things like black holes, neutron stars and white dwarfs. The trio would thereby be sensitive to the gravitational waves produced by small, dense objects orbiting one another, objects like white dwarfs, neutron stars and, most excitingly, black holes. A journey of simulations of Black Holes, Neutron Stars, White Dwarfs and Space and Time.
