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…

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…

Revised Masses for Low Density Planets Orbiting the Disordered M-dwarf System TOI-1266

Dakotah Tyler, Erik A. Petigura, James Rogers +5

We present an analysis of 126 new radial velocity measurements from the MAROON-X spectrograph to investigate the TOI-1266 system, which hosts two transiting sub-Neptunes at 10.8 an…

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…

Searching for GEMS: Characterizing Six Giant Planets around Cool Dwarfs

Shubham Kanodia, Arvind F. Gupta, Caleb I. Canas +42

Transiting giant exoplanets around M-dwarf stars (GEMS) are rare, owing to the low-mass host stars. However, the all-sky coverage of TESS has enabled the detection of an increasing…

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…

TOI-1685 b is a Hot Rocky Super-Earth: Updates to the Stellar and Planet Parameters of a Popular JWST Cycle 2 Target

Jennifer A. Burt, Matthew J. Hooton, Eric E. Mamajek +12

We present an updated characterization of the TOI-1685 planetary system, which consists of a P = 0.69\,day USP super-Earth planet orbiting a nearby ( = 37.6\,pc) M2.5…

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…
