Thermodynamics of Accretion in the Vicinity of Black Holes

Abstract:
Since the recognition that angular momentum transport in
accretion disks is due to MHD turbulence stirred by the
magneto-rotational instability, there has been tremendous progress in
understanding accretion dynamics. Comparatively less effort has been
expended on accretion thermodynamics, despite its direct connection to
observable properties. In this talk I will review some recent work in
this area, including the dynamical influence of radiation pressure,
the link between MHD turbulence and variability in the light output
(including relativistic modulation), and emissivity near the ISCO.
