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…

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…
