Methane on the temperate exo-Saturn TOI-199b
Aaron Bello-Arufe, Renyu Hu, Mantas Zilinskas +10
Temperate ( K) gas giants represent an unexplored frontier in exoplanet atmospheric spectroscopy. Orbiting a G-type star every days, the Saturn-mass exopl…
The KPF SURFS-UP Survey I: Transmission Spectroscopy of WASP-76 b
Aaron Householder, Fei Dai, Aurora Kesseli +25
We introduce the KPF SURFS-UP (Spectroscopy of the Upper-atmospheres and ReFractory Species in Ultra-hot Planets) Survey, a high-resolution survey to investigate the atmospheric co…
Volcanic Satellites Tidally Venting Na, K, SO2 in Optical & Infrared Light
Apurva V. Oza, Andrea Gebek, Moritz Meyer zu Westram +19
Recent infrared spectroscopy from the James Webb Space Telescope (JWST) has spurred analyses of common volcanic gases such as carbon dioxide (CO2), sulfur dioxide (SO2), alongside…
A water-rich interior in the temperate sub-Neptune K2-18 b revealed by JWST
Renyu Hu, Aaron Bello-Arufe, Armen Tokadjian +7
Temperate sub-Neptunes are compelling targets for detecting liquid-water oceans beyond the Solar System. If water-rich and lacking massive hydrogen-helium envelopes, these planets…
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…
Doppler Shifted Transient Sodium Detection by KECK/HIRES
Athira Unni, Apurva V. Oza, H. Jens Hoeijmakers +12
We carried out the first high-resolution transit observations of the exoplanet WASP-49 Ab with Keck/HIRES. Upon custom wavelength calibration we achieve a Doppler RV precision of $…
Limits on the atmospheric metallicity and aerosols of the sub-Neptune GJ 3090 b from high-resolution CRIRES+ spectroscopy
Luke T. Parker, João M. Mendonça, Hannah Diamond-Lowe +9
The sub-Neptune planets have no solar system analogues, and their low bulk densities suggest thick atmospheres containing degenerate quantities of volatiles and H/He, surrounding c…
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…
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…
