The Sydney Radio Star Catalogue is a catalogue of radio detected stars and stellar binary systems compiled and maintained by a team at the University of Sydney. It includes: main sequence stars, M and K dwarfs, ultracool dwarfs, magnetically chemically peculiar stars, binaries (e.g. symbiotic binaries and RS CVn) and more. It does not include sources such as novae or X-ray binaries.

We have included stars that have been detected in the radio at least once and are confirmed radio stars. This includes stars that have been detected as circularly polarised radio sources, have radio light curve variability consistent with radio star variability, or are the result of a cross-match with at least 98% reliability. We do not include candidate radio stars. For full details on the construction and inclusions of the catalogue please see Driessen et al. (2024) .

The sky map above shows the positions of the stars in this catalogue, the size of the points shows the Stokes I integrated flux density.
