Physics and Astronomy
Stony Brook University
Phil Armitage is a Professor in the Department of Physics and Astronomy at Stony Brook
University, and a Group Leader at the Center for Computational Astrophysics at the
Flatiron Institute. He received his Ph.D. from the University of Cambridge. Prior
to joining Stony Brook he worked at JILA, at the University of Colorado, Boulder.
Armitage's research focuses on the use of computational techniques to study problems
in theoretical astrophysics. He is interested in understanding the physical processes
involved in the formation of planetary systems, including the role of two fluid instabilities
in forming the first analogs of asteroids and comets, and the importance of radiation
hydrodynamic effects in the accretion of planetary envelopes. Other areas of current
work include the effect of magnetic fields on black hole accretion, and studies of
what happens when stars are tidally disrupted by supermassive black holes.
