A Pursuit of Optical Phase Curves with K2
Abstract
We have systematically searched for the planetary phase curves among the planets discovered by K2. Using the planetary parameters, we filter out the best candidates, and examine their light curves in detail for the potential presence of the phase curve. For our work, we consider light curves from two different detrending pipelines - EVEREST and K2SFF. In order to remove any stellar and systematics, we use different flattening techniques and perform a detailed injection-retrieval test in order to understand the reliability and completeness of our pipeline to extract the phase curve. In this talk, we report potential phase curves for five planets observed with K2, two of which appear to be robust. However, we find the phase curve fit parameters are not consistent with the known RV masses, and therefore dive deeper into the reasons why such discrepancies could arise and potential ways for mitigating them.
