Interests:
I am interested in stellar and planetary physics, and relativistic astrophysics. Recently I've been working on issues related to extrasolar planets (cooling models of gas giants, strongly irradiated atmospheres, ellipsoidal variability in solar-type stars, tidal heating), pulsation of white dwarfs (seismology and mode driving for accreting, pulsating white dwarfs in Cataclysmic Variables), and quasi-periodic oscillations from the accretion disks in black hole binaries (seismology of accretion tori, and wave excitation by MHD turbulence).
Selected Projects:
Nonlinear Damping of Tides in Stars, Planets & & Compact Objects
VSGC Aerospace Graduate Research Fellowship - George Trammell IV
Upper Atmospheres of Hot Jupiters: Planetary Magnetic Field, Photoionization and Interaction with the Stellar Wind
AS-VITA Nonlinear Damping of Tides in Stellar and Planetary Systems
Alfred P. Sloan Foundation Fellowship
VSGC Undergraduate Scholar Award - R. Mendez
The implications of my research are important to the astronomical community. The calculations will address whether massive satellites are long-lived, and elucidate their physical conditions. Theoretical ...
