Searching for GEMS: Three warm Saturns and a super-Jupiter orbiting four early M-dwarfs
Pranav H. Premnath, Paul Robertson, Shubham Kanodia +33
The paper confirms and characterizes four short-period giant exoplanets—including three Saturn-mass planets and one dense super‑Jupiter—transiting early M‑dwarf stars, using TESS p…
A Revised Mass and Period for the Habitable Zone super-Earth GJ 3378b: A Planet Straddling the Cosmic Shoreline
Paul Robertson, Michael Endl, William D. Cochran +18
The nearby ( pc) M4V star GJ~3378 is a target of our radial velocity (RV) exoplanet survey of fully convective stars in the Solar neighborhood with the near-infrared spect…
Searching for GEMS: Discovery of the Nearby Post-Common-Envelope Binary System TIC-460388167
Alexandra Boone, Henry A. Kobulnicky, Caleb I. Cañas +11
Short-period white dwarf+main-sequence binaries are Post-Common-Envelope Binaries (PCEB) that have survived a common envelope phase. Such systems, if detached and eclipsing, enable…
HET/HPF observations of Helium in warm, hot, and ultra-hot Jupiters
Jaume Orell-Miquel, Kyra Sampson, Caroline V. Morley +5
The near-infrared helium triplet line is a powerful tool for studying atmospheric escape processes of close-in exoplanets, especially irradiated gas giants. Line profile fitting pr…
A Century of Radial Velocity and Astrometric Monitoring of 70 Oph AB: New PFS Data and Constraints on Planetary Companions
Yiting Li, Michael R. Meyer, Skylar D'Angiolillo +29
At a distance of 5.1 pc, the 70 Oph AB binary star system is one of the most favorable targets for future direct imaging and astrometry missions surveying mature, terrestrial plane…
Stellar and orbital characterization of three low mass M dwarf binary stars with dynamical spectroscopy from the Habitable Zone Planet Finder
Suhani Surana, Chad F. Bender, Caleb I. Cañas +13
Theoretical models of low-mass stars continue to be discrepant with observations when used to examine the mass-radius relationship and other physical parameters of individual stars…
