Scientific paper

We propose to make 6 observations of the transits of the hot Jupiter planet HD 189733b and six observations of its secondary eclipse in order to detect variations of the times of transit/eclipse due to secondary planets in the system, if present. Spitzer is the best telescope for transit timing of this system, allowing nearly an order of magnitude better timing precision than HST or ground-based observations (for any transiting planet), as already demonstrated with prior Spitzer observations of this target. These observations will be sensitive to the presence of Mars-mass bodies in mean-motion resonance with the transiting planet. We will utilize the IRAC 8 micron camera as this has the best trade-off in stability and source brightness to allow for the highest timing precision. In addition we will constrain the eccentricity of the transiting planet and we will search for variations in the depth of the secondary eclipse which are predicted by models of weather on hot Jupiter planets.
