Black holes, neutron stars and white dwarfs

 

Black-holes, neutron stars, and white dwarfs are ideal laboratories for exploring the most extreme physics in the universe. In particular, these compact objects provide the best opportunity for probing the behaviour of matter under extreme conditions, high-gravity environments, and studying the physics of accretion: the most efficient form of energy production known. Accretion onto compact objects is an essential physical process to understand the universe, playing a crucial role in galactic and extra-galactic astronomy. This can be best studied in compact binaries, where a stellar-mass black-hole, a neutron star (for X-ray binaries), or a white dwarf (for cataclysmic variables) is accreting material from a stellar companion.
