| | Abstract When a star approaches a supermassive black hole closer than the tidal radius, the star can be deformed and even disrupted by the black hole tidal field. Such tidal disruption events (TDEs) can be used to probe quiescent supermassive black holes and help us understand accretion/jet physics around black holes. TDEs have been observed with telescopes in hard and soft X-ray, UV, optical, and radio wavebands. It is puzzling why some TDEs have X-ray temperature while others have only optical/UV emission. In this talk I will first give an introduction on basic TDE physics, then will talk about our recent work on how soft X-ray temperature TDEs can be produced from stars disrupted on deep plunging orbits. |
