Discovery of a Nearby Habitable Zone Super-Earth Candidate Amenable to Direct Imaging

Corey Beard, Paul Robertson, Jack Lubin +31

We present the discovery of GJ 251 c, a candidate super-Earth orbiting in the Habitable Zone (HZ) of its M dwarf host star. Using high-precision Habitable-zone Planet Finder (HPF)…

Time-resolved p-mode oscillations for subgiant HD 142091 with NEID at WIYN

Jacob K. Luhn, Paul Robertson, Samuel Halverson +22

Detections of Earth-analog planets in radial velocity observations are limited by stellar astrophysical variability occurring on a variety of timescales. Current state-of-the-art m…

TOI-6324b: An Earth-Mass Ultra-Short-Period Planet Transiting a Nearby M Dwarf

Rena A. Lee, Fei Dai, Andrew W. Howard +71

We report the confirmation of TOI-6324 b, an Earth-sized (1.059 0.041 R) ultra-short-period (USP) planet orbiting a nearby (20 pc) M dwarf. Using the newly com…

A Pair of Dynamically Interacting Sub-Neptunes Around TOI-6054

Maxwell A. Kroft, Thomas G. Beatty, Ian J. M. Crossfield +31

We confirm the planetary nature of a pair of transiting sub-Neptune exoplanets orbiting the bright F-type sub-giant star TOI-6054 (, ) as a part of the OrCAS radia…
