Shows the central region of our Milky Way galaxy, only about 25,000 light years from Earth, revealing hundreds of white dwarf stars, neutron stars, and black holes bathed in an incandescent fog of multimillion-degree gas. It's funny, because the more wacky combinations of stars and compact object (white dwarf, neutron star, or black hole) we find or imagine, the more remarkable evolutionary scenarios astronomers can conceive of playing out. In many binary star systems, the primary star is a compact object such as a black hole, a neutron star, or white dwarf. €�This tell-tale signal, called a quasi-periodic oscillation or QPO, is a characteristic feature of the accretion disks that often surround the most compact objects in the universe — white dwarf stars, neutron stars and black holes. Sources of gravitational waves could possibly include binary star systems composed of white dwarfs, neutron stars, or black holes. 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. 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. 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). In our case, the processes of energy generation and conversion are particularly complicated because of the exotic nature of black holes. When a star starts running out of fuel, it usually cools off and collapses into one of three compact forms, depending on its total mass, a White Dwarf a Neutron Star or a Black Hole. Such is the case of white dwarfs, neutron stars and black holes. Black holes, like neutron stars, white dwarfs and normal stars, also have strong magnetic fields that get even stronger the closer you get to the event horizon, or the point from which light cannot escape.
