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…
A transmission spectrum of the sub-Earth planet L98-59~b in 1.1-1.7 m
Mario Damiano, Renyu Hu, Thomas Barclay +20
With the increasing number of planets discovered by TESS, the atmospheric characterization of small exoplanets is accelerating. L98-59 is a M-dwarf hosting a multi-planet system, a…
The Exoplanet Modeling and Analysis Center at NASA Goddard
Joe P. Renaud, Eric Lopez, Jonathan Brande +8
The Exoplanet Modeling and Analysis Center (EMAC) at NASA Goddard Space Flight Center is a web-based catalog, repository, and integration platform for modeling and analysis resourc…
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…
Eureka!: An End-to-End Pipeline for JWST Time-Series Observations
Taylor J. Bell, Eva-Maria Ahrer, Jonathan Brande +12
is a data reduction and analysis pipeline for exoplanet time-series observations, with a particular focus on JWST data. Over the next 1-2 decades, JWST will purs…
First Detections of Exop(lan)ets: Observations and Follow-Ups of the Floofiest Transits on Zoom
Sabina Sagynbayeva, Briley L. Lewis, Graham M. Doskoch +16
With the proliferation of online Zoom meetings as a means of doing science in the 2020s, astronomers have made new and unexpected Target of Opportunity (ToO) observations. Chief am…
The TESS Triple-9 Catalog: 999 uniformly vetted candidate exoplanets
Luca Cacciapuoti, Veselin B. Kostov, Marc Kuchner +20
The Transiting Exoplanet Survey Satellite (TESS) has detected thousands of exoplanet candidates since 2018, most of which have yet to be confirmed. A key step in the confirmation p…
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…
