TOI-3785 b: A Low-Density Neptune Orbiting an M2-Dwarf Star
Luke C. Powers, Jessica Libby-Roberts, Andrea S. J. Lin +19
Using both ground-based transit photometry and high-precision radial velocity (RV) spectroscopy, we confirm the planetary nature of TOI-3785 b. This transiting Neptune orbits an M2…
TOI-3984 A b and TOI-5293 A b: two temperate gas giants transiting mid-M dwarfs in wide binary systems
Caleb I. Cañas, Shubham Kanodia, Jessica Libby-Roberts +30
We confirm the planetary nature of two gas giants discovered by TESS to transit M dwarfs with stellar companions at wide separations. TOI-3984 A () is an M4 dwarf hosting…
An In-Depth Look at TOI-3884b: a Super-Neptune Transiting a M4 Dwarf with Persistent Star Spot Crossings
Jessica E. Libby-Roberts, Maria Schutte, Leslie Hebb +25
We perform an in-depth analysis of the recently validated TOI-3884 system, an M4 dwarf star with a transiting super-Neptune. Using high precision light curves obtained with the 3.5…
The unusual M-dwarf Warm Jupiter TOI-1899~b: Refinement of orbital and planetary parameters
Andrea S. J. Lin, Jessica E. Libby-Roberts, Jaime A. Alvarado-Montes +31
TOI-1899 b is a rare exoplanet, a temperate Warm Jupiter orbiting an M-dwarf, first discovered by Cañas et al. (2020) from a TESS single-transit event. Using new radial velocities…
