The analysis combined TESS, NASA Exoplanet Archive, and ExoFOP data with EXOFAST computations on Harvard’s Canon cluster. The task was to connect observations with a model of the planet and star, while understanding the assumptions involved.
The analysis focused on the planet and its host star, using the fitted properties to investigate questions of potential habitability.
The research process
TESS photometry and archival information provide the starting measurements.
