The Search for Possible Orbital Decays of Hot Jupiters with Data from TESS and Foregone

The existence and large number of discoveries of hot Jupiters challenge the traditional core accretion theory, and there are two unproven hypotheses about the formation and development of hot Jupiters. In this paper, we attempt to provide new clues to support the hypotheses by looking for more possible evidence of hot Jupiters undergoing tidal orbital decay. Combining TESS data with previous astronomical observations creates new possibilities for discovering new candidates. The study found 24 hot Jupiters suspected of orbital decay, when eight of them have reached the point where the trends are clear enough and the data rich enough for further study, and compared them with similar findings made by their peers. This could provide direction for future research.
