A Testbed for Tidal Migration: the 3D Architecture of an Eccentric Hot Jupiter HD 118203 b Accompanied by a Possibly Aligned Outer Giant Planet
Jingwen Zhang, Daniel Huber, Lauren M. Weiss +31
Characterizing outer companions to hot Jupiters plays a crucial role in deciphering their origins. We present the discovery of a long-period giant planet, HD 118203 c ($m_{c}=11.79…
Nuggets of Wisdom: Determining an Upper Limit on the Number Density of Chickens in the Universe
Rachel Losacco, Zachary Claytor
The lower limit on the chicken density function (CDF) of the observable Universe was recently determined to be approximately 10 chickens pc. For over a year, however…
The TIME Table: Rotation and Ages of Cool Exoplanet Host Stars
Eric Gaidos, Zachary Claytor, Ryan Dungee +2
Age is a stellar parameter that is both fundamental and difficult to determine. Among middle-aged M dwarfs, the most prolific hosts of close-in and detectable exoplanets, gyrochron…
Kepler-102: Masses and Compositions for a Super-Earth and Sub-Neptune Orbiting an Active Star
Casey Brinkman, James Cadman, Lauren Weiss +24
Radial velocity (RV) measurements of transiting multiplanet systems allow us to understand the densities and compositions of planets unlike those in the Solar System. Kepler-102, w…
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 (…
TKS V. Twin sub-Neptunes Transiting the Nearby G Star HD 63935
Nicholas Scarsdale, Joseph M. Akana Murphy, Natalie M. Batalha +56
We present the discovery of two nearly identically-sized sub-Neptune transiting planets orbiting HD 63935, a bright ( mag), sun-like () star at 49 pc. TESS id…
The Second Discovery from the COol Companions ON Ultrawide orbiTS (COCONUTS) Program: A Cold Wide-Orbit Exoplanet around a Young Field M Dwarf at 10.9 pc
Zhoujian Zhang, Michael C. Liu, Zachary R. Claytor +3
We present the identification of the COCONUTS-2 system, composed of the M3 dwarf L 34-26 and the T9 dwarf WISEPA J075108.79763449.6. Given their common proper motions and parall…
A Guide to Realistic Uncertainties on Fundamental Properties of Solar-Type Exoplanet Host Stars
Jamie Tayar, Zachary R. Claytor, Daniel Huber +1
Our understanding of the properties and demographics of exoplanets critically relies on our ability to determine fundamental properties of their host stars. The advent of Gaia and…
The TESS-Keck Survey II: An Ultra-Short Period Rocky Planet and its Siblings Transiting the Galactic Thick-Disk Star TOI-561
Lauren M. Weiss, Fei Dai, Daniel Huber +61
We report the discovery of TOI-561, a multi-planet system in the galactic thick disk that contains a rocky, ultra-short period planet (USP). This bright () star hosts three…
