Follow Up Observations of TESS Exoplanets Using the Union College Observatory: Extended Mission

We are members of the TESS Observing Program Working Group (TFOP) in collaboration with other universities and observatories around the world in an effort to help in the extensive follow up observations needed for the Targets of Interest (TOI) of NASA's Transiting Exoplanet Survey Satellite (TESS). We contribute seeing-limited photometry where the goal is to provide time-series photometric observations that can remove false positives due to nearby eclipsing binary stars. Using the program AstroImageJ, we fully analyzed and submitted photometry for three TOIs. TOI 851.01 was retired as a Validated Planet Candidate. Submission of TOI 1319.01 confirmed a transit and candidate was retired as a Nearby Eclipsing Binary. For TOI 1371.01 we confirmed a partial transit and the candidate was retired as a Spectroscopic Binary. TESS mission has entered an extended mission and we continue to take observations throughout 2020.
