Novae flares

20 January 2022

At https://phys.org/news/2022-01-frequent-extreme-superflares-nova-v2487.html … photometric observations of a recurrent nova event, V2487ph, is displaying interesting behaviour. Superflares have been identified from the sources, occurring on a daily basis. More info at https://arxiv.org/abs/2201.04080 … or https://arxiv.org/pdf/2201.04080v1.pdf

Superflares are massive bursts of energy from a stellar surface. On the other hand, novae, including supernovas, are stellar explosions. Or that is the theory. Disturbingly, flares from this particular supernova have been intermittently seen over the last 18 years. What is going on? This nova doesn't seem to want to collapse, or explode. It is still highly active on the surface.
