Scientific paper

We present selected results of a Warm Spitzer campaign to observe exoplanetary candidates identified by the Kepler mission. The Spitzer light curves provide an independent test of the planetary nature of these candidates. We combine the results of the Spitzer observations with those from BLENDER (a software package to model Kepler light curves as astrophysical false positives) and spectroscopy (where available) to consider the planetary status of several candidates with putative radii between 1.5 and 3 times that of the Earth. Particularly in the cases of candidates with masses too small to be confirmed with radial velocity measurements, Spitzer observations provide crucial information about the planetary status of a given candidate, namely by establishing whether the transit depth is achromatic.
