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…

Automated all-sky detection of γ Doradus / δ Scuti hybrids in TESS data from positive unlabelled (PU) learning
Mykyta Kliapets, Pablo Huijse, Andrew Tkachenko +4
The Transiting Exoplanet Survey Satellite (TESS) mission has observed hundreds of millions of stars, substantially contributing to the available pool of high-precision photometric…

Evolution of the near-core rotation frequency of 2,497 intermediate-mass stars from their dominant gravito-inertial mode
Conny Aerts, Timothy Van Reeth, Joey S. G. Mombarg +1
We combined Gaia DR3 and TESS photometric light curves to estimate the internal physical properties of 2,497 gravity-mode pulsators. We relied on asteroseismic properties of Kepler…
