From Earths to Super-Earths: Five New Small Planets Transiting M Dwarf Stars
Jonathan Gomez Barrientos, Heather A. Knutson, Morgan Saidel +39
Earth-sized planets transiting M dwarf stars present one of the best opportunities with current facilities for studying the atmospheric and bulk compositions of terrestrial worlds.…
The James Webb Space Telescope NIRSpec-PRISM Transmission Spectrum of the Super-Puff, Kepler-51d
Jessica E. Libby-Roberts, Aaron Bello-Arufe, Zachory K. Berta-Thompson +14
Kepler-51 is a 500 Myr G dwarf hosting three "super-puffs" and one low-mass non-transiting planet. Kepler-51d, the coolest (T_eq ~ 350 K) transiting planet in this system, is also…
An Oxidation Gradient Straddling the Small Planet Radius Valley
Collin Cherubim, Robin Wordsworth, Dan Bower +3
We present a population-level view of volatile gas species (H, He, HO, O, CO, CO, CH) distribution during the sub-Neptune to rocky planet transition, revealing…
Characterising the Atmosphere of 55 Cancri e: 1D Forward Model Grid for Current and Future JWST Observations
Mantas Zilinskas, Christiaan van Buchem, Sebastian Zieba +9
Recent JWST observations with NIRCam and MIRI of the ultra-short-period super-Earth 55 Cancri e indicate a possible volatile atmosphere surrounding the planet. Previous analysis of…
TOI-6324b: An Earth-Mass Ultra-Short-Period Planet Transiting a Nearby M Dwarf
Rena A. Lee, Fei Dai, Andrew W. Howard +71
We report the confirmation of TOI-6324 b, an Earth-sized (1.059 0.041 R) ultra-short-period (USP) planet orbiting a nearby (20 pc) M dwarf. Using the newly com…
A New Spectral Library for Modeling the Surfaces of Hot, Rocky Exoplanets
Kimberly Paragas, Heather A. Knutson, Renyu Hu +7
JWST's MIRI LRS provides the first opportunity to spectroscopically characterize the surface compositions of close-in terrestrial exoplanets. Models for the bare-rock spectra of th…
Effects of planetary mass uncertainties on the interpretation of the reflectance spectra of Earth-like exoplanets
Mario Damiano, Zachary Burr, Renyu Hu +2
Atmospheric characterization of Earth-like exoplanets through reflected light spectroscopy is a key goal for upcoming direct imaging missions. A critical challenge in this endeavor…
Updated Mass, Eccentricity, and Tidal Heating Constraints for the Earth-sized Planet LP 791-18 d
Michael Greklek-McKeon, Heather A. Knutson, W. Garrett Levine +5
LP 791-18 d is a temperate Earth-sized planet orbiting a late M dwarf, surrounded by an interior super-Earth (LP 791-18 b, = 1.2 , days) and an exterior…
Evidence for a volcanic atmosphere on the sub-Earth L98-59b
Aaron Bello-Arufe, Mario Damiano, Katherine A. Bennett +8
Assessing the prevalence of atmospheres on rocky planets around M-dwarf stars is a top priority of exoplanet science. High-energy activity from M-dwarfs can destroy the atmospheres…
