We propose 4-band IRAC observations of a newly discovered transiting planet with an orbital period of 3.9 days, which is longer than any other known planet transiting a bright star. We will compare Spitzer photometry obtained in and out of secondary eclipse to measure thermal emission from the planet and to constrain models of irradiated giant planets. In 12 hours of observation with IRAC, we will measure the effective temperature of the planetary atmosphere and constrain the orbital eccentricity. We recently discovered this Jupiter-sized companion in our XO transit search program, obtaining a transit depth of 2% and a transit duration of 2.5 hours. Our initial radial velocity follow up rules out companions greater than a few Jupiter masses. We request ToO status for this program with the expectation that the Spitzer observations will proceed once we definitively measure the radial velocity amplitude and hence the companion mass. Thermal emission from this newly discovered planet that transits a V=11 solar-type star should be easier to detect than emission from Tres-1b and HD 209458b. We will compare IRAC photometry with existing 4.5 and 8.0 um data for Tres-1 and use the 3.6 and 5.6 um data to test model predictions regarding water and CO opacity in the planet's atmosphere.
