Content, progress and pedagogy of the module

A general introduction to the physics of binary star evolution. We start by the basic theory of determining binary star orbits and stellar masses. We investigate in detail mass transfer and mass loss from binary systems. An introduction to stellar evolution in binaries is given, before we focus on formation and evolution of high- and low-mass X-ray binaries and compare their observational properties with theory. We analyse radio pulsar binaries and binary systems with two compact objects (black holes, neutron stars, white dwarfs). We study kinematic effects of supernovae in binaries. Finally, we discuss gravitational waves and their astrophysical sources at low and high frequencies.
