HD~143811~AB is the host star to the directly imaged planet HD~143811~AB~b, which was recently discovered using data from the Gemini Planet Imager and Keck NIRC2. A member of the S…
Detection of an Earth-sized exoplanet orbiting the nearby ultracool dwarf star SPECULOOS-3
Michaël Gillon, Peter P. Pedersen, Benjamin V. Rackham +81
Located at the bottom of the main sequence, ultracool dwarf stars are widespread in the solar neighbourhood. Nevertheless, their extremely low luminosity has left their planetary p…
The TESS-Keck Survey XX: 15 New TESS Planets and a Uniform RV Analysis of all Survey Targets
Alex S. Polanski, Jack Lubin, Corey beard +69
The Transiting Exoplanet Survey Satellite (TESS) has discovered hundreds of new worlds, with TESS planet candidates now outnumbering the total number of confirmed planets from $\te…
Developing a Drift Rate Distribution for Technosignature Searches of Exoplanets
Megan G. Li, Sofia Z. Sheikh, Christian Gilbertson +4
A stable-frequency transmitter with relative radial acceleration to a receiver will show a change in received frequency over time, known as a "drift rate''. For a transmission from…
TOI-1801 b: A temperate mini-Neptune around a young M0.5 dwarf
M. Mallorquín, E. Goffo, E. Pallé +79
We report the discovery, mass, and radius determination of TOI-1801 b, a temperate mini-Neptune around a young M dwarf. TOI-1801 b was observed in TESS sectors 22 and 49, and the a…
Dynamical Architectures of S-type Transiting Planets in Binaries I: Target Selection using Hipparcos and Gaia proper motion anomalies
Jingwen Zhang, Lauren M. Weiss, Daniel Huber +16
The effect of stellar multiplicity on planetary architecture and orbital dynamics provides an important context for exoplanet demographics. We present a volume-limited catalog up t…
Overfitting Affects the Reliability of Radial Velocity Mass Estimates of the V1298 Tau Planets
Sarah Blunt, Adolfo Carvalho, Trevor J. David +23
Mass, radius, and age measurements of young (<100 Myr) planets have the power to shape our understanding of planet formation. However, young stars tend to be extremely variable in…
Inner Planetary System Gap Complexity is a Predictor of Outer Giant Planets
Matthias Y. He, Lauren M. Weiss
The connection between inner small planets and outer giant planets is crucial to our understanding of planet formation across a wide range of orbital separations. While Kepler prov…
A Mini-Neptune Orbiting the Metal-poor K Dwarf BD+29 2654
Fei Dai, Kevin C. Schlaufman, Henrique Reggiani +48
We report the discovery and Doppler mass measurement of a 7.4-day 2.3- mini-Neptune around a metal-poor K dwarf BD+29 2654 (TOI-2018). Based on a high-resolution Keck/HIR…
The TESS-Keck Survey. XV. Precise Properties of 108 TESS Planets and Their Host Stars
Mason G. MacDougall, Erik A. Petigura, Gregory J. Gilbert +38
We present the stellar and planetary properties for 85 TESS Objects of Interest (TOIs) hosting 108 planet candidates which comprise the TESS-Keck Survey (TKS) sample. We combine ph…
The Kepler Giant Planet Search. I: A Decade of Kepler Planet-host Radial Velocities from W. M. Keck Observatory
Lauren M. Weiss, Howard Isaacson, Andrew W. Howard +17
Despite the importance of Jupiter and Saturn to Earth's formation and habitability, there has not yet been a comprehensive observational study of how giant exoplanets correlate wit…
Astrometric Accelerations as Dynamical Beacons: A Giant Planet Imaged Inside the Debris Disk of the Young Star AF Lep
Kyle Franson, Brendan P. Bowler, Yifan Zhou +13
We present the direct imaging discovery of a giant planet orbiting the young star AF Lep, a 1.2 member of the 24 3 Myr Pic moving group. AF Lep was observed a…
A Dynamical Systems Approach to the Theory of Circumbinary Orbits in the Circular Restricted Problem
Andrew Langford, Lauren M. Weiss
To better understand the orbital dynamics of exoplanets around close binary stars, i.e., circumbinary planets (CBPs), we applied techniques from dynamical systems theory to a physi…
Evidence for the volatile-rich composition of a 1.5- planet
Caroline Piaulet, Björn Benneke, Jose M. Almenara +18
The population of planets smaller than approximately is widely interpreted as consisting of rocky worlds, generally referred to as super-Earths. This picture is larg…
Direct Imaging and Astrometric Detection of a Gas Giant Planet Orbiting an Accelerating Star
Thayne Currie, G. Mirek Brandt, Timothy D. Brandt +31
