Existence of uneven circumstellar matter found based on TESS data
Researchers from the Yunnan Observatories of the Chinese Academy of Sciences have discovered unusual variations in the consecutive Transiting Exoplanet Survey Satellite (TESS) light curves of the supersoft X-ray source V Sge. This is the first evidence to reveal that there may be uneven circumstellar matter surrounding the supersoft X-ray source.
