Finding TESS Objects of Interest in the CVZ Using Automated Pipeline DAVE
Abstract
Since the advent of the Transiting Exoplanet Survey Satellite (TESS), the large volume of transit data available demands for fast, accurate, and comprehensive methods in order to automate light curve analysis. The two continuous viewing zones (CVZs) of TESS, sky areas with ~350 days of continuous observation and ~100,000 targets, provide the unique opportunity to detect candidate exoplanets with long orbital period baselines. Here we present vetting results for exoplanet candidates we discovered in the CVZ of Cycle 1 as part of our Guest Investigator (GI) program (P.I. Quintana), which were added to 2-minute cadence observations. We used the automated vetting pipeline Discovery and Vetting of Exoplanets (DAVE), which is designed to evaluate the significance of potential transits and evaluate photometric contamination from background sources in order to distinguish between a true planet candidate and a false positive. Currently, 12 new community TESS objects of interest (cTOIs) as exoplanet candidates have been identified in CVZ of Cycle 1, with more candidates likely to be flagged in Cycle 2. DAVE significantly increases the speed and ease in vetting transits and will support public release to the scientific community, enabling the potential for quick follow-up with radial-velocities to confirm any candidates and allow for possible target prioritization for the James Webb Space Telescope (JWST)'s own overlapping CVZ.
