SUMMARY:S&A Colloquium: Laura Driessen (University of Sydney)
DESCRIPTION:The Sydney Radio Star Catalogue: a new catalogue of radio stars\n\nAbstract\n\nI will present a new catalogue of 839 radio stars detected < 3 GHz: the Sydney Radio Star Catalogue (SRSC). Most of these stars were identified using ASKAP. The ASKAP stars in the SRSC were found using a range of techniques: circular polarisation searches\, proper-motion searches\, variability searches and multiwavelength cross-matching. We have also included published radio stars from e.g. MeerKAT and V-LoTSS in the SRSC. The catalogue contains stars from across the Hertzsprung-Russell diagram\, from ultra-cool dwarfs to blue supergiants to Wolf Rayets. The previous best-known radio star catalogue\, the Wendker catalogue\, contained 228 radio stars detected < 3GHz. Hence the SRSC is a big leap forward in our understanding of the population and characteristics of radio stars. I will present an overview of the SRSC catalogue\, including the search methods\, the properties and types of stars\, the X-ray-radio characteristics using eROSITA_DE observations\, and the circular polarisation properties. I will also highlight some individual objects of particular interest. I will also present a short summary of ASKAP VAST\, with some recent updates. \nWatch recording\nEvent details\nDownload iCal\nCategory\nColloquia
