While the population of confirmed exoplanets continues to grow, the sample of confirmed transiting planets around evolved stars is still limited. We present the discovery and confirmation of a hot Jupiter orbiting TOI-2184 (TIC 176956893), a massive evolved subgiant (M ⋆ = 1.53 ± 0.12 M ⊙, R ⋆ = 2.90 ± 0.14 R ⊙) in the Transiting Exoplanet Survey Satellite (TESS) Southern Continuous Viewing Zone. The planet was flagged as a false positive by the TESS Quick-Look Pipeline due to periodic… 

TESS Giants Transiting Giants. II. The Hottest Jupiters Orbiting Evolved Stars

Giant planets on short-period orbits are predicted to be inflated and eventually engulfed by their host stars. However, the detailed timescales and stages of these processes are not well known. Here,

Constraining the Planet Occurrence Rate around Halo Stars of Potentially Extragalactic Origin

The search for planets orbiting other stars has recently expanded to include stars from galaxies outside the Milky Way. With the Transiting Exoplanet Survey Satellite (TESS) and Gaia surveys,

Sonification of TESS Data Validation Timeseries Files

In August 2022, the Transiting Exoplanet Survey Satelite (TESS) will start its fifth year of exploration having observed and analyzed more than a million stars in the search of extrasolar planets
