Indian astronomers detect ultraviolet emissions from novae in Andromeda galaxy

Astronomers from the Indian Institute of Astrophysics have made a significant discovery by detecting far ultraviolet emissions from novae in the Andromeda galaxy for the first time. This marks a new milestone in studying these stellar explosions. Using data from India's AstroSat satellite, the team identified ultraviolet emissions from 42 novae, including four during their outburst phase. This research allows for a better understanding of binary star systems in Andromeda. The findings reveal details about accretion disks around these stars, which are crucial for understanding how they interact with their companions. The study shows that the accretion process in these systems is stable over time.
