We present preliminary analysis of Spitzer IRAC observations of a candidate planet host white dwarf. The motion of the white dwarf as measured by changes in the arrival time of pulsations of this variable star are consistent with the presence of a planet with m.sin(i) 2 Jupiter masses with an orbital period 5 years. The low luminosity of the white dwarf offers an opportunity to confirm the existence of the planet with mid-infrared observations and a rare opportunity to directly study the light emitted by an extra-solar planet. This work is performed in part under contract with the Jet Propulsion Laboratory (JPL) funded by NASA through the Michelson Fellowship Program. JPL is managed for NASA by the California Institute of Technology.
