An Ultra-Short Period Super-Earth and Sub-Neptune Spanning the Radius Valley Orbiting the Kinematic Thick Disk Star TOI-2345
Yoshi Nike Emilia Eschen, Thomas G. Wilson, Andrea Bonfanti +94
A crucial chemical link between stars and their orbiting exoplanets is thought to exist. If universal, this connection could affect the formation and evolution of all planets. Ther…
Validation of TESS Planet Candidates with Multi-Color Transit Photometry and TRICERATOPS+
Jonathan Gomez Barrientos, Michael Greklek-McKeon, Heather A. Knutson +33
We present an upgraded version of TRICERATOPS, a software package designed to calculate false positive probabilities for planet candidates identified by the Transiting Exoplanet Su…
An Eccentric Sub-Neptune Moving Into the Evaporation Desert
Sydney Jenkins, Andrew Vanderburg, Ritika Sethi +31
Though missions such as Kepler, K2, and TESS have discovered 2,000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in (P3 days) orbits. T…
The NCORES Program: Precise planetary masses, null results, and insight into the planet mass distribution near the radius gap
David J. Armstrong, Ares Osborn, Remo Burn +39
NCORES was a large observing program on the ESO HARPS spectrograph, dedicated to measuring the masses of Neptune-like and smaller transiting planets discovered by the TESS satellit…
A Disintegrating Rocky World Shrouded in Dust and Gas: Mid-IR Observations of K2-22b using JWST
Nick Tusay, Jason T. Wright, Thomas G. Beatty +12
The disintegrating ultra-short period rocky exoplanet K2-22b periodically emits dusty clouds in a dynamically chaotic process resulting in a variable transit depth from 0-1.3%. The…
Two Earth-size Planets and an Earth-size Candidate Transiting the Nearby Star HD 101581
Michelle Kunimoto, Zifan Lin, Sarah Millholland +43
We report the validation of multiple planets transiting the nearby ( pc) K5V dwarf HD 101581 (GJ 435, TOI-6276, TIC 397362481). The system consists of at least two Earth-…
