摘要 (Abstract):

Novae are huge explosions on white dwarfs when sufficient materials are accreted on the surfaces. While the mechanism is rather simple, novae in the real world can be actually more complex than we expect. In this talk, I will show you several unique nova systems to demonstrate how extreme they could be. In addition, I will present the latest results from our group regarding gamma-ray emitting novae, which greatly improve our understanding on the crucial role that shocks play in powering nova emission and accelerating relativistic particles.
