Explore the Sydney Radio Star Catalogue!

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.

Included stars 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. Candidate radio stars are not included. For full details on the construction and inclusions of the catalogue please see Driessen et al. (2024) and peruse the data at radiostars.org.

In this interactive viewer, the Radio Stars are filterable by their observed frequencies. Toggle between 2D and 3D views for different perspectives in the sky and Milky Way galaxy, respectively. Hover over a unique star to see its name and distance. Crossfade between optical (visible light) and radio wavelengths in the 2D sky. Zoom in both modes and then zoom some more.
