TOI-1136 is a Young, Coplanar, Aligned Planetary System in a Pristine Resonant Chain
Fei Dai, Kento Masuda, Corey Beard +60
Convergent disk migration has long been suspected to be responsible for forming planetary systems with a chain of mean-motion resonances (MMR). Dynamical evolution over time could…
The TESS Grand Unified Hot Jupiter Survey. II. Twenty New Giant Planets
Samuel W. Yee, Joshua N. Winn, Joel D. Hartman +83
NASA's Transiting Exoplanet Survey Satellite (TESS) mission promises to improve our understanding of hot Jupiters by providing an all-sky, magnitude-limited sample of transiting ho…
TOI-561 b: A Low Density Ultra-Short Period "Rocky" Planet around a Metal-Poor Star
Casey Brinkman, Lauren M. Weiss, Fei Dai +22
TOI-561 is a galactic thick disk star hosting an ultra-short period (0.45 day orbit) planet with a radius of 1.37 R, making it one of the most metal-poor ([Fe/H] = -0.41…
TESS-Keck Survey XIV: Two giant exoplanets from the Distant Giants Survey
Judah E. Van Zandt, Erik A. Petigura, Mason MacDougall +42
We present the Distant Giants Survey, a three-year radial velocity (RV) campaign to measure P(DG|CS), the conditional occurrence of distant giant planets (DG; M_p ~ 0.3 - 13 M_J, P…
The TESS-Keck Survey. XIII. An Eccentric Hot Neptune with a Similar-Mass Outer Companion around TOI-1272
Mason G. MacDougall, Erik A. Petigura, Tara Fetherolf +58
We report the discovery of an eccentric hot Neptune and a non-transiting outer planet around TOI-1272. We identified the eccentricity of the inner planet, with an orbital period of…
Implicit biases in transit models using stellar pseudo-density
Gregory J. Gilbert, Mason G. MacDougall, Erik A. Petigura
The transit technique is responsible for the majority of exoplanet discoveries to date. Characterizing these planets involves careful modeling of their transit profiles. A common t…
Kepler-1656b's Extreme Eccentricity: Signature of a Gentle Giant
Isabel Angelo, Smadar Naoz, Erik Petigura +4
Highly eccentric orbits are one of the major surprises of exoplanets relative to the Solar System and indicate rich and tumultuous dynamical histories. One system of particular int…
The TESS-Keck Survey. XI. Mass Measurements for Four Transiting sub-Neptunes orbiting K dwarf TOI-1246
Emma V. Turtelboom, Lauren M. Weiss, Courtney D. Dressing +78
Multi-planet systems are valuable arenas for investigating exoplanet architectures and comparing planetary siblings. TOI-1246 is one such system, with a moderately bright K dwarf (…
The California-Kepler Survey. X. The Radius Gap as a Function of Stellar Mass, Metallicity, and Age
Erik A. Petigura, James G. Rogers, Howard Isaacson +10
In 2017, the California-Kepler Survey (CKS) published its first data release (DR1) of high-resolution optical spectra of 1305 planet hosts. Refined CKS planet radii revealed that s…
