Measuring the Obliquities of the TRAPPIST-1 Planets with MAROON-X
Madison Brady, Jacob Bean, Andreas Seifahrt +6
A star's obliquity with respect to its planetary system can provide us with insight into the system's formation and evolution, as well as hinting at the presence of additional obje…
MAROON-X: The first two years of EPRVs from Gemini North
Andreas Seifahrt, Jacob L. Bean, David Kasper +11
MAROON-X is a fiber-fed, optical EPRV spectrograph at the 8-m Gemini North Telescope on Mauna Kea, Hawai'i. MAROON-X was commissioned as a visiting instrument in December 2019 and…
TOI-561 b: A Low Density Ultra-Short Period "Rocky" Planet around a Metal-Poor Star
Casey Brinkman, Lauren M. Weiss, Fei Dai +22
TOI-561 is a galactic thick disk star hosting an ultra-short period (0.45 day orbit) planet with a radius of 1.37 R, making it one of the most metal-poor ([Fe/H] = -0.41…
TOI-1468: A system of two transiting planets, a super-Earth and a mini-Neptune, on opposite sides of the radius valley
P. Chaturvedi, P. Bluhm, E. Nagel +67
We report the discovery and characterization of two small transiting planets orbiting the bright M3.0V star TOI-1468 (LSPM J0106+1913), whose transit signals were detected in the p…
Unifying High- and Low-resolution Observations to Constrain the Dayside Atmosphere of KELT-20b/MASCARA-2b
David Kasper, Jacob L. Bean, Michael R. Line +10
We present high-resolution dayside thermal emission observations of the exoplanet KELT-20b/MASCARA-2b using the MAROON-X spectrograph. Applying the cross-correlation method with bo…
A detailed analysis of the Gl 486 planetary system
J. A. Caballero, E. Gonzalez-Alvarez, M. Brady +64
The Gl 486 system consists of a very nearby, relatively bright, weakly active M3.5 V star at just 8 pc with a warm transiting rocky planet of about 1.3 R_Terra and 3.0 M_Terra that…
A close-in puffy Neptune with hidden friends: The enigma of TOI 620
Michael A. Reefe, Rafael Luque, Eric Gaidos +82
We present the validation of a transiting low-density exoplanet orbiting the M2.5 dwarf TOI 620 discovered by the NASA TESS mission. We utilize photometric data from both TESS and…
