Thermal and Gravitational Tides in the Hot Jupiters
Phil Arras
University of Virginia
Many extrasolar planets are so close to their parent star that tides may
produce important effects, such as circularization of the orbit, and decay
of the orbit toward the star. After reviewing the observational motivation
for such tidal evolution, I'll discuss models for the structure and
thermal evolution of strongly irradiated gas giants, whose large observed
radii require a powerful "anomalous" heat source. I'll discuss possible
mechanisms for tides to produce such steady state heating. Lastly, I'll
discuss the possibility that close-in planets can have long-lived moons.
