Title: Thermal Emission from a Non-transiting Extrasolar Planet

Abstract: We propose Phoenix spectroscopy of the planet-hosting system tau Boo. Our target has the most favorable planet/star contrast of any bright (K < 6) system, and our data reduction will use a combination of new techniques designed to extract the faint planetary signal from the highly variable background. These observations will measure or set the first constraints on the thermal emission and atmospheric structure of this heretofore uncharacterized planet, testing atmospheric models ofirradiated giant planets in a surface-gravity regime neglected by current modeling efforts.
