K-dwarf starspot hunters: how to directly characterize spot and faculae properties with UV-IR panchromatic transit spectra
Joanna K. Barstow, Caitlyn Cullen, Yvonne Unruh +7
Transmission spectroscopy of exoplanets provides an important window into their atmospheric composition, structure and dynamics, especially in the JWST era. As the quality of the o…
JWST MEP - A World Under Spotty Starlight: Detection of CO2 and H2O in the Hot Saturn WASP-52b with JWST NIRSpec G395H
JWST GO 3969 Team, Yanbo Pan, Ryan J. MacDonald +21
Exoplanets orbiting active stars offer distinct challenges for atmospheric characterization with the JWST. Among such worlds, the hot Saturn WASP-52b (Teq 1300 K) orbits an…
Recovering the Morning and Evening Limbs of WASP-94Ab from Its Limb-Averaged JWST Transmission Spectrum
Tyler R. Fairnington, Michael Radica, Michael Zhang +5
Recent JWST observations have revealed that the morning and evening limbs of the hot Jupiter WASP-94Ab have very different transmission spectra. An analysis of these resolved limb…
The asymmetric limbs of HD 209458 b observed with JWST NIRCam F322W2/F444W
Cathal Maguire, Eva-Maria Ahrer, Charlotte Fairman +6
We present a reanalysis of JWST NIRCam F322W2/F444W transit observations of the hot Jupiter HD 209458 b to extract morning and evening transmission spectra. To determine whether as…
Atmospheric asymmetries in WASP-121 b revealed by rotational transits detected with JWST
Cyril Gapp, Aurélien Falco, Thomas M. Evans-Soma +6
Close-in exoplanets are tidally locked to their host star and thus exhibit extreme atmospheric temperature gradients. It has been theorized that the fraction of star light absorbed…
Characterizing Transiting Exoplanet Atmospheres in the 2030s with the Hubble Space Telescope
Joshua D. Lothringer, Hannah R. Wakeford, Robert C. Frazier +7
The Hubble Space Telescope inaugurated the era of exoplanet atmospheric characterization. While the James Webb Space Telescope has largely taken up the mantle of infrared atmospher…
KRONOS II: Solar-like Umbra and Penumbra Properties on the Young Sun V1298~Tau
Matthew M. Murphy, Adina D. Feinstein, Meir E. Schochet +14
Transiting exoplanets provide a unique laboratory for studying stellar surface heterogeneities via starspot or facular occultations. When observed at multiple wavelengths, this con…
The Neptunian ridge planet WASP-156 b does not have a polar orbit
M. Lafarga, J. I. Espinoza-Retamal, H. M. Cegla +26
The population of short-period exo-Neptunes is thought to be shaped by an interplay between different dynamical mechanisms, such as orbital migration and tidal effects, and photoev…
Super-Solar Metallicity and Tentative Evidence for Photochemistry on WASP-96b from JWST and Ground-Based VLT Transmission Spectroscopy
Michael Radica, Jake Taylor, Yoav Rotman +13
With its expanded wavelength coverage and increased precision compared to previous space-based observatories, JWST provides the opportunity to revisit benchmark planets and view th…
BOWIE-ALIGN: Exploring degeneracies in the muted transmission spectrum of the aligned hot Jupiter NGTS-2b with NIRSpec/G395H
Charlotte Fairman, Hannah R. Wakeford, Alastair B. Claringbold +15
We present the first atmospheric observation and characterisation of the aligned, 1468 K hot Jupiter, NGTS-2b, with one JWST NIRSpec/G395H transit. These observations complete the…
LRG-BEASTS: Detection of sodium and evidence for water absorption in the hot Saturn HAT-P-44b
Alastair B. Claringbold, Peter J. Wheatley, James Kirk +5
We present the low-resolution optical transmission spectrum of the inflated hot Saturn HAT-P-44b. The planet is a close sibling in radius (1.24 ), temperature (11…
BOWIE-ALIGN: Sub-solar C/O ratio and metallicity atmosphere of the misaligned hot Jupiter HAT-P-30b
Alastair B. Claringbold, Chloe E. Fisher, James Kirk +18
We present the JWST NIRSpec/G395H transmission spectrum of the misaligned hot Jupiter HAT-P-30b from 2.8--5.2 m as part of the BOWIE-ALIGN survey, a comparative survey designed…
