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…

Updated forecast for TRAPPIST-1 times of transit for all seven exoplanets incorporating JWST data

Eric Agol, Natalie H. Allen, Björn Benneke +12

The TRAPPIST-1 system has been extensively observed with JWST in the near-infrared with the goal of measuring atmospheric transit transmission spectra of these temperate, Earth-siz…

Hints of a sulfur-rich atmosphere around the 1.6 R Super-Earth L98-59 d from JWST NIRSpec G395H transmission spectroscopy

Amélie Gressier, Néstor Espinoza, Natalie H. Allen +11

Detecting atmospheres around planets with a radius below 1.6 R, commonly referred to as rocky planets (Rogers_2015, Rogers_2021), has proven to be challenging. However,…

Atmospheric retrievals suggest the presence of a secondary atmosphere and possible sulfur species on L 98-59 d from JWST NIRSpec G395H transmission spectroscopy

Agnibha Banerjee, Joanna K. Barstow, Amélie Gressier +10

L 98-59 d is a Super-Earth planet orbiting an M-type star. We performed retrievals on the transmission spectrum of L 98-59 d obtained using NIRSpec G395H during a single transit, f…

A warm Neptune's methane reveals core mass and vigorous atmospheric mixing

David K. Sing, Zafar Rustamkulov, Daniel P. Thorngren +18

Observations of transiting gas giant exoplanets have revealed a pervasive depletion of methane, which has only recently been identified atmospherically. The depletion is thought to…
