A Partially Eclipsing Triple in the Kepler Field Exhibiting Doppler Beaming

To date, the Kepler Space Telescope has discovered 3872 exoplanets with an additional 2454 Kepler objects of Interest (KOIs). Using publicly available HiRes spectra along with Kepler photometry we present a detailed analysis of a peculiar KOI. Through a simultaneous spectroscopic and photometric analysis this system has been determined to most likely consist of a central K-dwarf along with two ultra-short period M-dwarfs that collectively orbit the central host star in a highly inclined s-type orbit. The small M-dwarfs eclipse each other, but not the central host star indicating a significant non-coplanarity of the orbits. Finally, the reflex motion of the host star leads to relativistic Doppler beaming appearing in the photometric time series, which allows for the estimation of the mass of the companions.
