A Spatial Map of the Atmospheric Limb of a Hot Jupiter

Lili Alderson, Hannah R. Wakeford, David Grant +18

Planets are inherently three-dimensional objects shaped by their thermal structure and dynamics. Observations of transiting exoplanets have begun to uncover this three-dimensional…

Leveraging Impact Parameter to Mitigate the Transit Light Source Effect: Early Insights from TRAPPIST-1

Ana Glidden, Alexander I. Shapiro, Sara Seager +19

Stellar activity complicates exoplanet transmission spectra, particularly for smaller planets around M dwarfs with JWST. The transit light source (TLS) effect, the imprinting of sp…

JWST TRAPPIST-1 e/b Program: Motivation and first observations

Natalie H. Allen, Néstor Espinoza, V. A. Boehm +24

One of the forefront goals in the field of exoplanets is the detection of an atmosphere on a temperate terrestrial exoplanet, and among the best suited systems to do so is TRAPPIST…

JWST-TST DREAMS: The Nightside Emission and Chemistry of WASP-17b

Jacob Lustig-Yaeger, Kristin S. Sotzen, Kevin B. Stevenson +24

Theoretical studies have suggested using planetary infrared excess (PIE) to detect and characterize the thermal emission of transiting and non-transiting exoplanets, however the PI…

JWST-TST DREAMS: Sulfur dioxide in the atmosphere of the Neptune-mass planet HAT-P-26 b from NIRSpec G395H transmission spectroscopy

Amélie Gressier, Natasha E. Batalha, Nicholas Wogan +24

We present the James Webb Space Telescope (JWST) transmission spectrum of the exoplanet HAT-P-26 b (18.6 Earth masses, 6.33 Earth radii), based on a single transit observed with th…

JWST-TST DREAMS: NIRSpec/PRISM Transmission Spectroscopy of the Habitable Zone Planet TRAPPIST-1 e

Néstor Espinoza, Natalie H. Allen, Ana Glidden +32

TRAPPIST-1 e is one of the very few rocky exoplanets that is both amenable to atmospheric characterization and that resides in the habitable zone of its star -- located at a distan…

JWST-TST DREAMS: Secondary Atmosphere Constraints for the Habitable Zone Planet TRAPPIST-1 e

Ana Glidden, Sukrit Ranjan, Sara Seager +25

The TRAPPIST-1 system offers one of the best opportunities to characterize temperate terrestrial planets beyond our own solar system. Within the TRAPPIST-1 system, planet e stands…

Warm, water-depleted rocky exoplanets with surface ionic liquids: A proposed class for planetary habitability

Rachana Agrawal, Sara Seager, Iaroslav Iakubivskyi +6

The discovery of thousands of exoplanets and the emergence of telescopes capable of exoplanet atmospheric characterization have intensified the search for habitable worlds. Due to…

JWST-TST DREAMS: A Precise Water Abundance for Hot Jupiter WASP-17b from the NIRISS SOSS Transmission Spectrum

Dana R. Louie, Elijah Mullens, Lili Alderson +27

Water has proven to be ubiquitously detected in near-infrared (NIR) transmission spectroscopy observations of hot Jupiter atmospheres, including WASP-17b. However, previous analyse…

JWST-TST DREAMS: A Super-Solar Metallicity in WASP-17 b Dayside Atmosphere from NIRISS SOSS Eclipse Spectroscopy

Amélie Gressier, Ryan J. MacDonald, Néstor Espinoza +26

We present the first emission spectrum of the hot Jupiter WASP-17 b using one eclipse observation from the JWST Near Infrared Imager and Slitless Spectrograph (NIRISS) Single Objec…

JWST-TST DREAMS: Non-Uniform Dayside Emission for WASP-17b from MIRI/LRS

Daniel Valentine, Hannah R. Wakeford, Ryan C. Challener +23

We present the first spectroscopic characterisation of the dayside atmosphere of WASP-17b in the mid-infrared using a single JWST MIRI/LRS eclipse observation. From forward-model f…

JWST-TST High Contrast: Achieving direct spectroscopy of faint substellar companions next to bright stars with the NIRSpec IFU

Jean-Baptiste Ruffio, Marshall D. Perrin, Kielan K. W. Hoch +33

The JWST NIRSpec integral field unit (IFU) presents a unique opportunity to observe directly imaged exoplanets from 3-5 um at moderate spectral resolution (R~2,700) and thereby bet…

JWST-TST DREAMS: Quartz Clouds in the Atmosphere of WASP-17b

David Grant, Nikole K. Lewis, Hannah R. Wakeford +39

Clouds are prevalent in many of the exoplanet atmospheres that have been observed to date. For transiting exoplanets, we know if clouds are present because they mute spectral featu…
