Validating and Updating Ephemerides of Transiting Exoplanets with the Thacher Observatory

We present the latest results from Thacher’s exoplanet observational campaign which has the goals of updating ephemerides, measuring transit parameters, and helping to validate exoplanets as part of the TESS Follow-Up Observation Program Sub-Group 1 and Exoplanet Watch, a NASA citizen science program. We validate our data reduction methods by comparing results obtained through our own custom transit reduction and fitting pipeline, Exoplanet Transit Interpretation Code Software (EXOTIC), and AstroImageJ (AIJ) applied to three high-priority TESS and Exoplanet Watch targets: TIC281837575.01, TIC142381532.01, and KPS-1b.
