Abstract
Abstract: Kostov et al. (2021) report the discovery of the first transiting circumbinary planet, detected from a single sector of TESS data. ARCES observations played a role in helping to establish the parameters of the system. We briefly present an overview of this interesting planetary system and then discuss the challenges encountered in analyzing ARCES data to derive accurate radial velocities for this project.
