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…
TESS Giants Transiting Giants III: An eccentric warm Jupiter supports a period-eccentricity relation for giant planets transiting evolved stars
Samuel K. Grunblatt, Nicholas Saunders, Ashley Chontos +27
The fate of planets around rapidly evolving stars is not well understood. Previous studies have suggested that relative to the main sequence population, planets transiting evolved…
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…
GJ 3929: High Precision Photometric and Doppler Characterization of an Exo-Venus and its Hot, Mini-Neptune-mass Companion
Corey Beard, Paul Robertson, Shubham Kanodia +31
We detail the follow up and characterization of a transiting exo-Venus identified by TESS, GJ 3929b, (TOI-2013b) and its non-transiting companion planet, GJ 3929c (TOI-2013c). GJ 3…
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…
The TESS Grand Unified Hot Jupiter Survey. I. Ten TESS Planets
Samuel W. Yee, Joshua N. Winn, Joel D. Hartman +69
We report the discovery of ten short-period giant planets (TOI-2193A b, TOI-2207 b, TOI-2236 b, TOI-2421 b, TOI-2567 b, TOI-2570 b, TOI-3331 b, TOI-3540A b, TOI-3693 b, TOI-4137 b)…
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 (…
TOI-1696 and TOI-2136: Constraining the Masses of Two Mini-Neptunes with HPF
Corey Beard, Paul Robertson, Shubham Kanodia +29
We present the validation of two planets orbiting M dwarfs, TOI-1696b and TOI-2136b. Both planets are mini-Neptunes orbiting nearby stars, making them promising prospects for atmos…
A close-in puffy Neptune with hidden friends: The enigma of TOI 620
Michael A. Reefe, Rafael Luque, Eric Gaidos +82
We present the validation of a transiting low-density exoplanet orbiting the M2.5 dwarf TOI 620 discovered by the NASA TESS mission. We utilize photometric data from both TESS and…
Rotational modulation of spectroscopic Zeeman signatures in low-mass stars
Ryan C. Terrien, Allison Keen, Katy Oda +24
Accurate tracers of the stellar magnetic field and rotation are cornerstones for the study of M dwarfs and for reliable detection and characterization of their exoplanetary compani…
An eccentric Brown Dwarf eclipsing an M dwarf
Caleb I. Cañas, Suvrath Mahadevan, Chad F. Bender +16
We report the discovery of a brown dwarf transiting the early M dwarf TOI-2119 on an eccentric orbit () at an orbital period of $7.2008…
The TESS-Keck Survey. VIII. Confirmation of a Transiting Giant Planet on an Eccentric 261 day Orbit with the Automated Planet Finder Telescope
Paul A. Dalba, Stephen R. Kane, Diana Dragomir +72
We report the discovery of TOI-2180 b, a 2.8 giant planet orbiting a slightly evolved G5 host star. This planet transited only once in Cycle 2 of the primary Transiting…
TESS Giants Transiting Giants II: The hottest Jupiters orbiting evolved stars
Samuel K. Grunblatt, Nicholas Saunders, Meng Sun +42
Giant planets on short-period orbits are predicted to be inflated and eventually engulfed by their host stars. However, the detailed timescales and stages of these processes are no…
