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…

Elemental Abundances of Kepler Objects of Interest in APOGEE DR17

Aida Behmard, Melissa Ness, Emily C. Cunningham +1

The elemental abundances of planet host stars can shed light on the conditions of planet forming environments. We test if individual abundances of 130 known/candidate planet hosts…

Planet Engulfment Detections are Rare According to Observations and Stellar Modeling

Aida Behmard, Fei Dai, John M. Brewer +2

Dynamical evolution within planetary systems can cause planets to be engulfed by their host stars. Following engulfment, the stellar photosphere abundance pattern will reflect accr…

Planet Engulfment Signatures in Twin Stars

Aida Behmard, Jason Sevilla, Jim Fuller

Planet engulfment can be inferred from enhancement of refractory elements in the photosphere of the engulfing star following accretion of rocky planetary material. Such refractory…

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…
