New and Updated Rossiter-McLaughlin Measurements for Three Hot Jupiter-Hosting M Dwarfs
Drew Weisserman, Ryan Cloutier, Alexandra Rochon +12
Evidence suggests that Kozai-Lidov high-eccentricity migration (HEM) is the dominant migration channel for short-period Giant Exoplanets around M dwarf Stars (GEMS). However, it is…
A Pair of Warm Saturn-mass Planets near the 2:1 Mean Motion Resonance around TOI-3850
Sean Collins, Michelle Kunimoto, Nicolas B. Cowan +24
Warm Jupiters, with orbital periods of -- and radii exceeding , are a relatively understudied class of exoplanets occupying the parameter space bet…
RV and TTV Measurements of Two Transiting Long-Period Giants around TOI-4600
Tong Hu, Zitao Lin, Sharon X. Wang +27
TOI-4600b and c, originally identified by the Transiting Exoplanet Survey Satellite (TESS) and reported by I. Mireles et al. (2023), are a rare pair of transiting long-period giant…
Searching for GEMS: TOI-5349b is a Saturn-like planet orbiting a metal-rich early M-dwarf
Angeli Sandoval, Caleb I. Cañas, Shubham Kanodia +27
We report the confirmation and analysis of TOI-5349b, a transiting, warm, Saturn-like planet orbiting an early M-dwarf with a period of 3.3 days, which we confirmed as part o…
The JWST Rocky Worlds DDT Program reveals GJ 3929b to likely be a bare rock
Qiao Xue, Michael Zhang, Brandon P. Coy +14
We report first results from the JWST Rocky Worlds Director's Discretionary Time program. Two secondary eclipses of the terrestrial exoplanet GJ 3929b were recently observed using…
An Earth-like Density for the Temperate Earth-sized Planet GJ 12b
Madison Brady, Jacob Bean, Ritvik Basant +9
While JWST has provided us with the opportunity to probe the atmospheres of potentially-habitable planets, observations of the TRAPPIST-1 system have shown us that active stars sev…
