New paradigms for radiatively efficient accretion disks

5th Floor Classroom (CCA)

5th Floor Classroom


162 5th Ave Flatiron Institute CCA, 5th Floor New York, NY 10010


Computational advances in the simulation of radiatively efficient accretion disks suggest that it may soon be feasible to replace parameterized disk models with ones based on first principles physics. Doing so will require understanding the interplay of radiation physics, net magnetic flux, self-gravity, and dynamical effects. The workshop will bring together theorists and computational modelers to review recent progress in disk simulations and discuss next steps.
