GCM Constraints on the Detectability of the CO-CH Biosignature Pair on TRAPPIST-1e with JWST
Yoav Rotman, Thaddeus D. Komacek, Geronimo L. Villanueva +2
Terrestrial exoplanets such as TRAPPIST-1e will be observed in a new capacity with JWST/NIRSpec, which is expected to be able to detect CO, CH, and O signals, if presen…
The effect of interior heat flux on the atmospheric circulation of hot and ultra-hot Jupiters
Thaddeus D. Komacek, Peter Gao, Daniel P. Thorngren +2
Many hot and ultra-hot Jupiters have inflated radii, implying that their interiors retain significant entropy from formation. These hot interiors lead to an enhanced internal heat…
Water and an escaping helium tail detected in the hazy and methane-depleted atmosphere of HAT-P-18b from JWST NIRISS/SOSS
Guangwei Fu, Néstor Espinoza, David K. Sing +11
JWST is here. The early release observation program (ERO) provides us with the first look at the scientific data and the spectral capabilities. One of the targets from ERO is HAT-P…
Early Release Science of the exoplanet WASP-39b with JWST NIRCam
Eva-Maria Ahrer, Kevin B. Stevenson, Megan Mansfield +96
Measuring the metallicity and carbon-to-oxygen (C/O) ratio in exoplanet atmospheres is a fundamental step towards constraining the dominant chemical processes at work and, if in eq…
A strong H- opacity signal in the near-infrared emission spectrum of the ultra-hot Jupiter KELT-9b
Bob Jacobs, Jean-Michel Désert, Lorenzo Pino +11
We present the analysis of a spectroscopic secondary eclipse of the hottest transiting exoplanet detected to date, KELT-9b, obtained with the Wide Field Camera 3 aboard the Hubble…
Identification of carbon dioxide in an exoplanet atmosphere
The JWST Transiting Exoplanet Community Early Release Science Team, Eva-Maria Ahrer, Lili Alderson +129
Carbon dioxide (CO2) is a key chemical species that is found in a wide range of planetary atmospheres. In the context of exoplanets, CO2 is an indicator of the metal enrichment (i.…
Greater climate sensitivity and variability on TRAPPIST-1e than Earth
Assaf Hochman, Paolo De Luca, Thaddeus D. Komacek
The atmospheres of rocky exoplanets are close to being characterized by astronomical observations, in part due to the commissioning of the James Webb Space Telescope. These observa…
Patchy nightside clouds on ultra-hot Jupiters: General Circulation Model simulations with radiatively active cloud tracers
Thaddeus D. Komacek, Xianyu Tan, Peter Gao +1
The atmospheres of ultra-hot Jupiters have been characterized in detail through recent phase curve and low- and high-resolution emission and transmission spectroscopic observations…
A New Analysis of 8 Spitzer Phase Curves and Hot Jupiter Population Trends: Qatar-1b, Qatar-2b, WASP-52b, WASP-34b, and WASP-140b
Erin May, Kevin Stevenson, Jacob Bean +16
With over 30 phase curves observed during the warm Spitzer mission, the complete data set provides a wealth of information relating to trends and three-dimensional properties of ho…
TESS Giants Transiting Giants II: The hottest Jupiters orbiting evolved stars
Samuel K. Grunblatt, Nicholas Saunders, Meng Sun +42
Giant planets on short-period orbits are predicted to be inflated and eventually engulfed by their host stars. However, the detailed timescales and stages of these processes are no…
Strong HO and CO emission features in the spectrum of KELT-20b driven by stellar UV irradiation
Guangwei Fu, David K. Sing, Joshua D. Lothringer +7
Know thy star, know thy planetary atmosphere. Every exoplanet with atmospheric measurements orbits around a star, and the stellar environment directly affects the planetary atmosph…
