The Occurrence Rate of Nearby Planetary Companions to Hot Jupiters
Lizhou Sha, Andrew M. Vanderburg, Chelsea X. Huang +33
The paper measures how often hot Jupiters have nearby transiting companion planets using TESS data, finding an occurrence rate of about 8%, which informs theories of hot‑Jupiter fo…
Hydrogen airglow from an escaping ultrahot Jupiter atmosphere
Yapeng Zhang, Chenliang Huang, Aaron Householder +17
Intense high-energy irradiation of close-in gaseous exoplanets drives the rapid escape of their atmospheres, fundamentally shaping planetary demographics. While atmospheric loss is…
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…
A Test of Substellar Evolutionary Models with High-Precision Ages from Asteroseismology and Gyrochronology for the Benchmark System HR 7672AB
Yaguang Li, Michael C. Liu, Trent J. Dupuy +35
We present high-precision measurements for HR~7672AB, composed of a Sun-like (G0V) star and an L~dwarf companion. Three nights of precise (70 cm/s) radial velocity (RV) asteroseism…
Extreme winds on the emerging dayside of an ultrahot Jupiter
Yapeng Zhang, Joost P. Wardenier, Aaron Householder +16
High-resolution spectroscopy provides a unique opportunity to directly probe atmospheric dynamics by resolving Doppler shifts of planetary signal as a function of orbital phases. U…
From Earths to Super-Earths: Five New Small Planets Transiting M Dwarf Stars
Jonathan Gomez Barrientos, Heather A. Knutson, Morgan Saidel +39
Earth-sized planets transiting M dwarf stars present one of the best opportunities with current facilities for studying the atmospheric and bulk compositions of terrestrial worlds.…
