Objectives

This project used Spitzer Space Telescope observations of nearby stars to search for giant planets in wide orbits. We surveyed stars within 8pc in the Spitzer IRAC 2 band (4.5 microns) with two epochs to identify commoving companions to stars. The goal was to find cold (Teff<400K) giant planets at distances up to 1500AU. A survey model based on the population of wide planetary mass companions found in star forming regions suggested approximately 8 cold planets would be found by the survey. Any individual objects discovered would be excellent follow-up targets for JWST to further study the atmospheres of cold giant planets.
