DETECTION OF THERMAL EMISSION FROM A SUPER-EARTH
Astrophysical Journal Letters
We report on the detection of infrared light from the super-Earth 55 Cnc e, based on four occultations obtained with Warm Spitzer at 4.5 microns. Our data analysis consists of a two-part process. In a first step, we perform individual analyses of each dataset and compare several baseline models to optimally account for the systematics affecting each lightcurve. We apply independent photometric correction techniques, including polynomial detrending and pixel-mapping, that yield consistentdoi:10.1088/2041-8205/751/2/l28 fatcat:dgq37mv5sjg75gcpmegdl5d4we
