Migration and Evolution of giant ExoPlanets (MEEP) I: Nine Newly Confirmed Hot Jupiters from the TESS Mission
Jack Schulte, Joseph E. Rodriguez, Allyson Bieryla +72
Hot Jupiters were many of the first exoplanets discovered in the 1990s, but in the decades since their discovery, the mysteries surrounding their origins remain. Here, we present n…
A super-Earth and a mini-Neptune near the 2:1 MMR straddling the radius valley around the nearby mid-M dwarf TOI-2096
F. J. Pozuelos, M. Timmermans, B. V. Rackham +72
Several planetary formation models have been proposed to explain the observed abundance and variety of compositions of super-Earths and mini-Neptunes. In this context, multitransit…

Noah Vowell, Joseph E. Rodriguez, Samuel N. Quinn +41
We present the discovery and characterization of HIP 33609 b, a transiting warm brown dwarf orbiting a late B star, discovered by NASA's Transiting Exoplanet Survey Satellite TESS…
TESS Discovery of Twin Planets near 2:1 Resonance around Early M-Dwarf TOI 4342
Evan Tey, Chelsea X. Huang, Michelle Kunimoto +28
With data from the Transiting Exoplanet Survey Satellite (TESS), we showcase improvements to the MIT Quick-Look Pipeline (QLP) through the discovery and validation of a multi-plane…
VaTEST II: Statistical Validation of 11 TESS-Detected Exoplanets Orbiting K-type Stars
Priyashkumar Mistry, Kamlesh Pathak, Aniket Prasad +48
NASA's Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission designed to find transiting exoplanets orbiting nearby bright stars. It has identified more than 32…
Radial velocity confirmation of a hot super-Neptune discovered by TESS with a warm Saturn-mass companion
E. Knudstrup, D. Gandolfi, G. Nowak +59
We report the discovery and confirmation of the planetary system TOI-1288. This late G dwarf harbours two planets: TOI-1288 b and TOI-1288 c. We combine TESS space-borne and ground…
TESS discovery of a super-Earth and two sub-Neptunes orbiting the bright, nearby, Sun-like star HD 22946
Luca Cacciapuoti, Laura Inno, Giovanni Covone +51
We report the Transiting Exoplanet Survey Satellite (TESS) discovery of a three-planet system around the bright Sun-like star HD~22946(V=8.3 mag),also known as TIC~100990000, locat…
The TESS-Keck Survey. XI. Mass Measurements for Four Transiting sub-Neptunes orbiting K dwarf TOI-1246
Emma V. Turtelboom, Lauren M. Weiss, Courtney D. Dressing +78
Multi-planet systems are valuable arenas for investigating exoplanet architectures and comparing planetary siblings. TOI-1246 is one such system, with a moderately bright K dwarf (…
