Revisiting the Exo-Mercury Candidate GJ 367 b with ESPRESSO and a Self-Consistent Tidal Distortion Model
Rena A. Lee, Fei Dai, Ellen M. Price +18
We report revised mass and radius measurements for GJ 367 b, an ultra-short-period (7.7 hr) sub-Earth in a multi-planet system orbiting a nearby (~9 pc) M dwarf host. Previous mass…
The NUV transit of XO-3 b
Raven Cilley, Lia Corrales, George W. King +8
Near-UV (NUV) measurements of exoplanet transits offer a means to probe atmospheric escape, cloud formation, and planetary magnetic fields. We examine a 2024 XMM-Newton Optical Mon…
Stellar separation shapes spin-orbit alignment in visual binaries
Michael Poon, Dang Pham, Marta L. Bryan +2
Stellar binaries may form through several formation pathways, including disk or core fragmentation. Their spin-orbit angles are a signature of formation, although individual measur…
Planet-Planet Scattering Explains the Mass-Eccentricity Relation of Warm Jupiters
Jiayin Dong, Eve J. Lee, Eiichiro Kokubo +2
Warm giant planets with orbital periods of tens of days exhibit a positive correlation between mass and eccentricity. We interpret this trend as the outcome of planet-planet scatte…
The Orbital Eccentricity--Radius Distribution for Warm, Single Planets in TESS
Tyler R. Fairnington, Jiayin Dong, Chelsea X. Huang +40
We characterize the radius-dependent eccentricity distribution of 219 warm (P = 8--50 days) systems with only one transiting planetary candidate identified during Sectors 1-69 of t…
The NEID Earth Twin Survey. IV. Confirming an 89 d, Planet Orbiting a Nearby Sun-like Star
Mark R. Giovinazzi, Evan Fitzmaurice, Arvind F. Gupta +19
We present the confirmation of HD 190360 d, a warm (), low-mass () planet orbiting the nearb…
