JWST Transmission Spectroscopy of TOI-3235 b: Challenges in Constraining Giant Planet Atmospheres Around M Dwarfs Amid Stellar Contamination
Zoe Ko, Néstor Espinoza, Andrés Jordán +7
Giant planets orbiting low-mass M dwarfs challenge current planet formation theories, which predict that such planets are unlikely to form. Characterizing their atmospheres can pro…
Charge Migration and Residual Non-Linearity in NIRSpec BOTS Observations
Munazza K. Alam, Leonardo Ubeda, Qinyan +3
We investigate the effect of charge migration and residual non-linearity on the JWST/NIRSpec G395H NRS1 and NRS2 detectors using Bright Object Time Series (BOTS) observations of th…
JWST NIRSpec finds no clear signs of an atmosphere on TOI-1685 b
Chloe E. Fisher, Matthew J. Hooton, Amélie Gressier +21
Determining the prevalence of atmospheres on terrestrial planets is a core objective in exoplanetary science. While M dwarf systems offer a promising opportunity, conclusive observ…
Tracing the Winds: A Uniform Interpretation of Helium Escape in Exoplanets from Archival Spectroscopic Observations
Patrick McCreery, Leonardo A. Dos Santos, Néstor Espinoza +2
Over the past decade, observations of evaporating exoplanets have become increasingly common, driven by the discovery of the near-infrared helium-triplet line as a powerful probe o…
Discovery and Characterization of an Eccentric, Warm Saturn Transiting the Solar Analog TOI-4994
Romy Rodriguez Martinez, Jason D. Eastman, Karen Collins +46
We present the detection and characterization of TOI-4994b (TIC 277128619b), a warm Saturn-sized planet discovered by the NASA Transiting Exoplanet Survey Satellite (TESS). TOI-499…
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…
Toward Exoplanet Transit Spectroscopy Using JWST/MIRI's Medium Resolution Spectrometer
Drake Deming, Guangwei Fu, Jeroen Bouwman +9
The Mid-Infrared Instrument (MIRI)'s Medium Resolution Spectrometer (the MRS) on JWST has potentially important advantages for transit and eclipse spectroscopy of exoplanets, inclu…
HST SHEL: Enabling Comparative Exoplanetology with HST/STIS
Natalie H. Allen, David K. Sing, Néstor Espinoza +12
The Hubble Space Telescope (HST) has been our most prolific tool to study exoplanet atmospheres. As the age of JWST begins, there is a wealth of HST archival data that is useful to…
Non-Detections of Helium in the Young Sub-Jovian Planets K2-100b, HD 63433b, & V1298 Tau c
Munazza K. Alam, James Kirk, Leonardo A. Dos Santos +10
We search for excess in-transit absorption of neutral helium at 1.083 m in the atmospheres of the young (<800 Myr) sub-Jovian (0.2-0.5 ) planets HD 63433b, K2-100b, a…
