Description
The dynamic environment which exists in black hole accretion discs has traditionally been probed in stellar-mass Galactic black holes where the timescale for changes is short. In principle, if the quantity of material in a disc around a super-massive black hole is small and is not replenished, then the disc will drain on a timescale of a few hundred days and the system can pass through several states during a short monitoring campaign. Partial tidal disruption events, where the atmosphere of a star is stripped and consumed by a nuclear black hole, gives us the perfect opportunity to test whether disc states and state changes are mass-invariant? We present some recent results.
