GEMS JWST: Hold on to your HATS(-6 b), a sub-solar metallicity giant planet with water, methane and ammonia in its atmosphere
Giannina Guzmán Caloca, Caleb I. Cañas, Nicole L. Wallack +16
HATS-6 b is one of several recently discovered Giant Exoplanets orbiting M-dwarf Stars (GEMS) and is part of a JWST survey that aims to compare bulk and atmospheric properties of t…
A Climate-Constrained Bayesian Inverse Method for JWST Rocky Exoplanet Eclipse Spectra: A Case Study of LTT 1445A b
Nicholas Wogan, Natasha Batalha, Jegug Ih +2
Determining whether temperate rocky exoplanets orbiting M stars retain atmospheres is currently a central goal of exoplanet astronomy. To this end, the James Webb Space Telescope h…
The effect of spectral resolution on biosignature detection via reflected light observations of the Earth through time
Samantha Gilbert-Janizek, Jacob Lustig-Yaeger, Joshua Krissansen-Totton
NASA's Habitable Worlds Observatory (HWO) will search for biosignatures on Earth-like exoplanets using reflected light spectroscopy. A critical instrument design parameter is resol…
GEMS JWST: HATS-75 b -- A giant planet with a sub-solar metallicity atmosphere orbiting an M-dwarf
Reza Ashtari, Jacob Lustig-Yaeger, Jessica Libby-Roberts +12
HATS-75 b is one of the recently discovered Giant Exoplanets orbiting M-dwarf Stars (GEMS) with a transmission spectrum shaped by both its atmosphere and the active stellar surface…
Three outstanding physical questions for K2-18 b and other temperate sub-Neptunes
Shang-Min Tsai, Piero Ferrari, Mats Kuipers +7
Recent transmission spectra of the temperate sub-Neptune K2-18 b obtained with JWST have attracted significant attention. Debates have quickly arisen over the interpretation of the…
GEMS JWST: A sub-Solar metallicity atmosphere for giant planet TOI-5293Ab orbiting a rapidly changing M-dwarf
Shubham Kanodia, Caleb I. Cañas, Jacob Lustig-Yaeger +13
The growing sample of Giant Exoplanets around M-dwarf Stars (GEMS) helps probe the extremes of giant planet formation. Comparing the properties of this sample with their FGK counte…
What's Inside Matters: The Effect of Oxygen Fugacity and Initial Volatile Abundance on the Atmospheres of the TRAPPIST-1 Planets
Junellie Perez, Laura K. Schaefer, Edward Schwieterman +3
The TRAPPIST-1 planets have become prime targets for studying the atmospheric and geophysical properties of planets around M-dwarf stars. To effectively identify their atmospheric…
Surface pressure impact on nitrogen-dominated USP super-Earth atmospheres
Jamila Chouqar, Jacob Lustig-Yaeger, Zouhair Benkhaldoun +3
In this paper, we compare the chemistry and the emission spectra of nitrogen-dominated cool, warm, and hot ultra-short-period (USP) super-Earth atmospheres in and out of chemical e…
Properties of Sub-Neptune Atmospheres: TOI-270 System
J. Chouqar, Z. Benkhaldoun, A. Jabiri +3
We investigate the potential for the James Webb Space Telescope (JWST) to detect and characterize the atmospheres of the sub-Neptunian exoplanets in the TOI-270 system. Sub-Neptune…
Gaseous Mean Opacities for Giant Planet and Ultracool Dwarf Atmospheres over a Range of Metallicities and Temperatures
Richard S. Freedman, Jacob Lustig-Yaeger, Jonathan J. Fortney +3
We present new calculations of Rosseland and Planck gaseous mean opacities relevant to the atmospheres of giant planets and ultracool dwarfs. Such calculations are used in modeling…
