An Obliquity Measurement of the Hot Neptune TOI-1694b
Luke B. Handley, Andrew W. Howard, Ryan A. Rubenzahl +9
We present spectral observations of the multiplanet host TOI-1694 during the transit of TOI-1694b, a 26.1 hot Neptune with a 3.77-day orbit. By analyzing radial velociti…
HD 119130 b is not an "ultra-dense" sub-Neptune
Joseph M. Akana Murphy, Rafael Luque, Natalie M. Batalha +13
We present a revised mass measurement for HD 119130 b (aka K2-292 b), a transiting planet ( days, ) orbiting a chro…
The Compositions of Rocky Planets in Close-in Orbits Tend to be Earth-Like
Casey L. Brinkman, Lauren M. Weiss, Daniel Huber +54
Hundreds of exoplanets between 1-1.8 times the size of the Earth have been discovered on close in orbits. However, these planets show such a diversity in densities that some appear…
Precise and Accurate Mass and Radius Measurements of Fifteen Galactic Red Giants in Detached Eclipsing Binaries
D. M. Rowan, K. Z. Stanek, C. S. Kochanek +9
Precise and accurate mass and radius measurements of evolved stars are crucial to calibrating stellar models. Stars in detached eclipsing binaries (EBs) are excellent potential cal…
Asteroseismology of the Nearby K-Dwarf Draconis using the Keck Planet Finder and TESS
Marc Hon, Daniel Huber, Yaguang Li +76
Asteroseismology of dwarf stars cooler than the Sun is very challenging due to the low amplitudes and rapid timescales of oscillations. Here, we present the asteroseismic detection…
Discovery of a Jupiter Analog Misaligned to the Inner Planetary System in HD 73344
Jingwen Zhang, Lauren M. Weiss, Daniel Huber +6
We present the discovery of a Jupiter-like planet, HD 73344 d (, AU, ) based on…
KPF Confirms a Polar Orbit for KELT-18 b
Ryan A. Rubenzahl, Fei Dai, Samuel Halverson +24
We present the first spectroscopic transit results from the newly commissioned Keck Planet Finder on the Keck-I telescope at W. M. Keck Observatory. We observed a transit of KELT-1…
Obliquity Constraints for the Extremely Eccentric Sub-Saturn Kepler-1656 b
Ryan A. Rubenzahl, Andrew W. Howard, Samuel Halverson +25
The orbits of close-in exoplanets provide clues to their formation and evolutionary history. Many close-in exoplanets likely formed far out in their protoplanetary disks and migrat…
An Earth-sized Planet on the Verge of Tidal Disruption
Fei Dai, Andrew W. Howard, Samuel Halverson +95
TOI-6255~b (GJ 4256) is an Earth-sized planet (1.079 ) with an orbital period of only 5.7 hours. With the newly commissioned Keck Planet Finder (KPF) and CARMEN…
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 ($m_{c}=11.79…
The OATMEAL Survey. I. Low Stellar Obliquity in the Transiting Brown Dwarf System GPX-1
Steven Giacalone, Fei Dai, J. J. Zanazzi +31
We introduce the OATMEAL survey, an effort to measure the obliquities of stars with transiting brown dwarf companions. We observed a transit of the close-in ($P_{\rm orb} = 1.74 \,…
