Two Thousand Kepler Phase Curves from Phasma
Abstract
An exoplanet's optical phase curve constrains the thermal emission and albedo of the planet's surface and/or atmosphere, as well as potentially constraining the mass via gravitational influences on the host star. Recently, Jansen & Kipping (2018) demonstrated that exoplanets with precisely constrained orbital periods, as is typical of transiting planets, enable one to exploit a Fourier-argument to non-parametrically separate optical phase curves from long-term photometric time series in the presence of realistic noise structures. This algorithm, dubbed phasma, was applied to 477 confirmed exoplanets in the original paper. In this research note, we extend the sample to all non-false positive Kepler Objects of Interest with periods less than ten days. Our sample of 1998 detrended phase curves are made publicly available to help the community search for various effects. A Python port of the phasma code is also made available.
