A Small Brown Dwarf in an Aligned Orbit around a Young, Fully-Convective M Star
M. Brady, J. Bean, G. Stefánsson +6
A star's spin-orbit angle can give us insight into a system's formation and dynamical history. In this paper, we use MAROON-X observations of the Rossiter-McLaughlin (RM) effect to…
A Fourth Planet in the Kepler-51 System Revealed by Transit Timing Variations
Kento Masuda, Jessica E. Libby-Roberts, John H. Livingston +49
Kepler-51 is a -old Sun-like star hosting three transiting planets with radii - and orbital periods -$130\,\mathrm{day…
TOI-3568 b: a super-Neptune in the sub-Jovian desert
E. Martioli, R. P. Petrucci, E. Jofre +42
The sub-Jovian desert is a region in the mass-period and radius-period parameter space, typically encompassing short-period ranges between super-Earths and hot Jupiters, that exhib…
TESS Giants Transiting Giants. VI. Newly Discovered Hot Jupiters Provide Evidence for Efficient Obliquity Damping after the Main Sequence
Nicholas Saunders, Samuel K. Grunblatt, Ashley Chontos +53
The degree of alignment between a star's spin axis and the orbital plane of its planets (the stellar obliquity) is related to interesting and poorly understood processes that occur…
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…
The Aligned Orbit of a Hot Jupiter around the M Dwarf TOI-4201
Tianjun Gan, Sharon X. Wang, Fei Dai +12
Measuring the obliquities of stars hosting giant planets may shed light on the dynamical history of planetary systems. Significant efforts have been made to measure the obliquities…
HATS-38 b and WASP-139 b join a growing group of hot Neptunes on polar orbits
Juan I. Espinoza-Retamal, Guðmundur Stefánsson, Cristobal Petrovich +9
We constrain the sky-projected obliquities of two low-density hot Neptune planets, HATS-38 b and WASP-139 b, orbiting nearby G and K stars using Rossiter-McLaughlin (RM) observatio…
Early Results from the HUMDRUM Survey: A Small, Earth-mass Planet Orbits TOI-1450A
M. Brady, J. Bean, A. Seifahrt +23
M dwarf stars provide us with an ideal opportunity to study nearby small planets. The HUMDRUM (HUnting for M Dwarf Rocky planets Using MAROON-X) survey uses the MAROON-X spectrogra…
The death of Vulcan: NEID reveals the planet candidate orbiting HD 26965 is stellar activity
Abigail Burrows, Samuel Halverson, Jared C. Siegel +17
We revisit the long-studied radial velocity (RV) target HD26965 using recent observations from the NASA-NSF 'NEID' precision Doppler facility. Leveraging a suite of classical activ…
Searching for Giant Exoplanets around M-dwarf Stars (GEMS) I: Survey Motivation
Shubham Kanodia, Caleb I. Cañas, Suvrath Mahadevan +13
Recent discoveries of transiting giant exoplanets around M-dwarf stars (GEMS), aided by the all-sky coverage of TESS, are starting to stretch theories of planet formation through t…
