The Refined Transit Ephemeris of TOI-2180 b
The Transiting Exoplanet Survey Satellite (TESS) observed a single transit of the giant exoplanet TOI-2180 b in Sector 19 of its primary mission. A subsequent effort to characterize this system found that the orbital period of TOI-2180 b is 260.8 ± 0.6 days. This level of precision precludes most efforts to detect future transits and to further understand this exoplanet. We present a new transit of TOI-2180 b observed by TESS in Sector 48 and update the planet's transit ephemeris with its precisely measured orbital period. The refined ephemeris enables future transit observations to explore this planet's atmosphere or to search for rings or moons.
