SUMMARY:Accretion within the innermost stable circular orbit of Kerr black
  holes  -  Andrew Mummery (Oxford)

DESCRIPTION:Abstract: Classical relativistic theories of accretion are art
 ificially curtailed at the ISCO (innermost stable circular orbit) with all
  observable quantities set to zero between this radius and the black hole'
 s event horizon. Real accretion flows (as well as those in simulations) do
  not behave in this manner and remain hot and (potentially) observable unt
 il right up against the black hole's event horizon. In this talk I will di
 scuss a new theoretical approach which allows existing accretion theories 
 to be extended through the ISCO. I will highlight a number of remarkable s
 elf-similar properties of these solutions\, which show no explicit depende
 nce on the black hole's spin parameter. Finally\, I will discuss how exist
 ing "viscous" theories exterior to the ISCO may need to be revisited to be
 tter model the turbulent nature of an accretion flow near to the ISCO.
