The Turbulent Dynamics of Accretion Disks
  OKC colloquia

Tuesday 19 May 2015
from 13:15 to 15:00
at FB41
Speaker : Martin Pessah (Copenhagen)
Abstract : Accretion disks are flattened, differentially rotating gaseous structures that can be found surrounding young stars, white dwarfs, neutron starts, and black holes. Understanding the physical processes that determine the rate at which matter accretes and energy is radiated in these disks is vital for unraveling the formation, evolution, and fate of almost every type of object in the Universe. These processes are regulated by the rate at which angular momentum can be transported outwards. It is currently thought that the transport of angular momentum is mediated by magnetohydrodynamic turbulence. In this talk, I will give an overview of some of the basic ideas that have been around for the last few decades and will discuss the state-of-the-art in our understanding of angular momentum transport in turbulent, magnetized accretion disks.
