Early evidence for isotropic planetary obliquities in young super-Jupiter systems
Michael Poon, Marta L. Bryan, Hanno Rein +3
This decade has seen the first measurements of extrasolar planetary obliquities, characterizing how an exoplanet's spin axis is oriented relative to its orbital axis. These measure…
SiO and a super-stellar C/O ratio in the atmosphere of the giant exoplanet WASP-121b
Thomas M. Evans-Soma, David K. Sing, Joanna K. Barstow +15
Refractory elements such as iron, magnesium, and silicon can be detected in the atmospheres of ultrahot giant planets. This provides an opportunity to quantify the amount of refrac…

We confirm TOI-4201 b as a transiting Jovian mass planet orbiting an early M dwarf discovered by the Transiting Exoplanet Survey Satellite. Using ground based photometry and precis…
TOI-1859b: A 64-Day Warm Jupiter on an Eccentric and Misaligned Orbit
Jiayin Dong, Songhu Wang, Malena Rice +31
Warm Jupiters are close-in giant planets with relatively large planet-star separations (i.e., ). Given their weak tidal interactions with their host stars, meas…
A Hierarchical Bayesian Framework for Inferring the Stellar Obliquity Distribution
Jiayin Dong, Daniel Foreman-Mackey
Stellar obliquity, the angle between a planet's orbital axis and its host star's spin axis, traces the formation and evolution of a planetary system. In transiting exoplanet observ…
A High-Eccentricity Warm Jupiter Orbiting TOI-4127
Arvind F. Gupta, Jonathan M. Jackson, Guillaume Hebrard +36
We report the discovery of TOI-4127 b, a transiting, Jupiter-sized exoplanet on a long-period ( d), high-eccentricity orbit around a late F-type…
A JWST NIRSpec Phase Curve for WASP-121b: Dayside Emission Strongest Eastward of the Substellar Point and Nightside Conditions Conducive to Cloud Formation
Thomas Mikal-Evans, David K. Sing, Jiayin Dong +10
We present the first exoplanet phase curve measurement made with the JWST NIRSpec instrument, highlighting the exceptional stability of this newly-commissioned observatory for exop…
Longterm Stability of Planetary Systems formed from a Transitional Disk
Rory Bowens, Andrew Shannon, Rebekah Dawson +1
Transitional disks are protoplanetary disks with large and deep central holes in the gas, possibly carved by young planets. Dong, R., & Dawson, R. 2016, ApJ, 825, 7 simulated syste…
Statistical Analysis of the Dearth of Super-eccentric Jupiters in the Kepler Sample
Jonathan M. Jackson, Rebekah I. Dawson, Billy Quarles +1
Hot Jupiters may have formed in situ, or been delivered to their observed short periods through one of two categories of migration mechanisms: disk migration or high-eccentricity m…
NEID Reveals that The Young Warm Neptune TOI-2076 b Has a Low Obliquity
Robert C. Frazier, Gudmundur Stefansson, Suvrath Mahadevan +27
TOI-2076 b is a sub-Neptune-sized planet () that transits a young () bright () K-dwarf hosting a system of three transiting…
TOI-4562 b: A highly eccentric temperate Jupiter analog orbiting a young field star
Alexis Heitzmann, George Zhou, Samuel N. Quinn +47
We report the discovery of TOI-4562 b (TIC-349576261), a Jovian planet orbiting a young F7V-type star, younger than the Praesepe/Hyades clusters (< Myr). This planet stands o…
TOI-3757 b: A low density gas giant orbiting a solar-metallicity M dwarf
Shubham Kanodia, Jessica Libby-Roberts, Caleb I. Canas +32
We present the discovery of a new Jovian-sized planet, TOI-3757 b, the lowest density planet orbiting an M dwarf (M0V). It orbits a solar-metallicity M dwarf discovered using TESS…
NEID Rossiter-McLaughlin Measurement of TOI-1268b: A Young Warm Saturn Aligned with Its Cool Host Star
Jiayin Dong, Chelsea X. Huang, George Zhou +56
Close-in gas giants present a surprising range of stellar obliquity, the angle between a planet's orbital axis and its host star's spin axis. It is unclear whether the obliquities…
