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…

JWST unveils a high mean molecular weight atmosphere for mini-Neptune TOI-1130b: Evidence for formation beyond the water ice line

Saugata Barat, Tyler Fairnington, Shelby Courreges +21

We present the combined JWST/NIRSpec G395H and NIRISS SOSS transmission spectrum of a warm mini-Neptune, TOI-1130b (3.66 R, 19.8 M, K). It is…

Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903

Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173

Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…

A Cool Earth-sized Planet Candidate Transiting a Tenth Magnitude K-dwarf From K2

Alexander Venner, Andrew Vanderburg, Chelsea X. Huang +7

The transit method is currently one of our best means for the detection of potentially habitable "Earth-like" exoplanets. In principle, given sufficiently high photometric precisio…

The Eccentricity Distribution of Warm Sub-Saturns in TESS

Tyler R. Fairnington, Jiayin Dong, Chelsea X. Huang +45

We present the eccentricity distribution of warm sub-Saturns (4-8 Re, 8-200 day periods) as derived from an analysis of transit light curves from NASA's Transiting Exoplanet Survey…

TOI-2005b: An Eccentric Warm Jupiter in Spin-Orbit Alignment

Allyson Bieryla, Jiayin Dong, George Zhou +36

We report the discovery and characterization of TOI-2005b, a warm Jupiter on an eccentric (e~0.59), 17.3-day orbit around a V_mag = 9.867 rapidly rotating F-star. The object was de…
