Accretion physics in compact binaries

The study of accretion onto compact stellar remnants (white dwarfs, neutron stars and black holes) is one of the key areas in stellar astrophysics at UCT. It includes the study of Cataclysmic Variables, low-mass X-ray binaries and high-mass X-ray binaries. Researchers in this group lead the MeerKAT Large Survey Project on image-domain radio transients (ThunderKAT) and co-lead the MeerLICHT project for optical-radio transients.
