Autor: Adams, Elisabeth R., Jackson, Brian, Sickafoose, Amanda A., Morgenthaler, Jeffrey P., Worters, Hannah, Stubbers, Hailey, Carlson, Dallon, Bhure, Sakhee, Dekeyser, Stijn, Huang, Chelsea, Weinberg, Nevin N.

Ultra-hot Jupiters are likely doomed by tidal forces to undergo orbital decay and eventual disruption by their stars, but the timescale over which this process unfolds is unknown. We present results from a long-term project to monitor ultra-hot Jupit
