Hubble Space Telescope transmission spectroscopy for the temperate sub-Neptune TOI-270d: a possible hydrogen-rich atmosphere containing water vapour
Thomas Mikal-Evans, Nikku Madhusudhan, Jason Dittmann +6
TOI-270d is a temperate sub-Neptune discovered by the Transiting Exoplanet Survey Satellite (TESS) around a bright (J=9.1mag) M3V host star. With an approximate radius of 2RE and e…
Early Release Science of the exoplanet WASP-39b with JWST NIRISS
Adina D. Feinstein, Michael Radica, Luis Welbanks +86
Transmission spectroscopy provides insight into the atmospheric properties and consequently the formation history, physics, and chemistry of transiting exoplanets. However, obtaini…
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…
Early Release Science of the Exoplanet WASP-39b with JWST NIRSpec G395H
Lili Alderson, Hannah R. Wakeford, Munazza K. Alam +89
Measuring the abundances of carbon and oxygen in exoplanet atmospheres is considered a crucial avenue for unlocking the formation and evolution of exoplanetary systems. Access to a…
Early Release Science of the exoplanet WASP-39b with JWST NIRSpec PRISM
Z. Rustamkulov, D. K. Sing, S. Mukherjee +91
Transmission spectroscopy of exoplanets has revealed signatures of water vapor, aerosols, and alkali metals in a few dozen exoplanet atmospheres. However, these previous inferences…
Signatures of Strong Magnetization and Metal-Poor Atmosphere for a Neptune-Size Exoplanet
Lotfi Ben-Jaffel, Gilda E. Ballester, Antonio García Muñoz +10
The magnetosphere of an exoplanet has yet to be unambiguously detected. Investigations of star-planet interaction and neutral atomic hydrogen absorption during transit to detect ma…
Photochemically-produced SO in the atmosphere of WASP-39b
Shang-Min Tsai, Elspeth K. H. Lee, Diana Powell +82
Photochemistry is a fundamental process of planetary atmospheres that regulates the atmospheric composition and stability. However, no unambiguous photochemical products have been…
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.…
GJ 1252b: A Hot Terrestrial Super-Earth With No Atmosphere
Ian J. M. Crossfield, Matej Malik, Michelle L. Hill +16
The increasing numbers of rocky, terrestrial exoplanets known to orbit nearby stars (especially M dwarfs) has drawn increased attention to the possibility of studying these planets…
The Hubble PanCET Program: A Featureless Transmission Spectrum for WASP-29b and Evidence of Enhanced Atmospheric Metallicity on WASP-80b
Ian Wong, Yayaati Chachan, Heather A. Knutson +19
We present a uniform analysis of transit observations from the Hubble Space Telescope and Spitzer Space Telescope of two warm gas giants orbiting K-type stars - WASP-29b and WASP-8…
Solar-to-supersolar sodium and oxygen absolute abundances for a "hot Saturn" orbiting a metal-rich star
Nikolay K. Nikolov, David K. Sing, Jessica J. Spake +10
We present new analysis of infrared transmission spectroscopy of the cloud-free hot-Saturn WASP-96b performed with the Hubble and Spitzer Space Telescopes (HST and Spitzer). The WA…
The Hubble PanCET program: Emission spectrum of hot Jupiter HAT-P-41b
Guangwei Fu, David K. Sing, Drake Deming +6
We present the most complete emission spectrum for inflated hot Jupiter HAT-P-41b combining new HST WFC/G141 spectrum from the Hubble Panchromatic Comparative Exoplanet Treasury (P…
Diurnal variations in the stratosphere of the ultrahot giant exoplanet WASP-121b
Thomas Mikal-Evans, David K. Sing, Joanna K. Barstow +9
The temperature profile of a planetary atmosphere is a key diagnostic of radiative and dynamical processes governing the absorption, redistribution, and emission of energy. Observa…
A Mirage or an Oasis? Water Vapor in the Atmosphere of the Warm Neptune TOI-674 b
Jonathan Brande, Ian J. M. Crossfield, Laura Kreidberg +14
We report observations of the recently discovered warm Neptune TOI-674 b (5.25 \rearth{}, 23.6 \mearth{}) with the Hubble Space Telescope's Wide Field Camera 3 instrument. TOI-674…
