Hot Rocks Survey VI: An anomalously hot dayside for the rocky planet GJ 357 b
Merlin Zgraggen, Brice-Olivier Demory, Hannah Diamond-Lowe +15
As part of the JWST Hot Rocks Survey, we analyzed a JWST/MIRI F1500W secondary-eclipse observation of GJ 357 b, a rocky exoplanet orbiting a nearby M dwarf. We also performed a new…
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…
JWST-SUPER I: New insights into irradiated warm Neptunes atmospheres from MIRI observations of HD 106315 c
A. Dyrek, R. Waters, S. -M. Tsai +17
Sulphur-bearing molecules have recently emerged as powerful tracers of atmospheric photochemistry in exoplanets observed with JWST. In several warm giant planets, SO has been d…
A Homogeneous Survey of JWST MIRI Transmission Spectra of 10 Exoplanets
Martin Binet, Nikku Madhusudhan, Måns Holmberg +1
The launch of JWST has enabled unprecedented atmospheric characterization of exoplanets. In particular, the JWST-MIRI instrument in the mid-infrared enables probing of molecular sp…
Transmission Spectrum of the Benchmark Temperate Exo-Neptune TOI-1231 b
Subhajit Sarkar, Nikku Madhusudhan, Lorenzo Pica-Ciamarra +4
The JWST is revolutionizing our understanding of the temperate sub-Neptune population through atmospheric spectroscopy. The nature of these planets remains debated, as their bulk p…
The Mid-Infrared Transmission Spectrum of the Temperate Sub-Neptune TOI-270 d
Måns Holmberg, Nikku Madhusudhan, Martin Binet +3
Observations of temperate sub-Neptunes with JWST have ushered in a new era for atmospheric characterization of small exoplanets. In particular, the MIRI instrument provides a uniqu…
Hot Rocks Survey V: Secondary Eclipse Photometry of GJ 3473 b with JWST/MIRI
Måns Holmberg, Hannah Diamond-Lowe, João M. Mendonça +16
JWST is transforming our ability to characterise small exoplanets, from sub-Neptunes to rocky worlds. A key open question is whether highly irradiated rocky planets can retain atmo…
A JWST Transmission Spectrum of the Temperate Sub-Neptune TOI-732 c
Frances E. Rigby, Nikku Madhusudhan, Subhajit Sarkar +3
In recent years, JWST has facilitated detections of carbon-bearing molecules in the atmospheres of temperate sub-Neptunes orbiting M dwarfs, ushering in a new era in the characteri…
The atmospheric composition of TOI-270 d
Savvas Constantinou, Nikku Madhusudhan, Måns Holmberg
The first explorations of temperate sub-Neptune exoplanets have been the hallmark of early JWST observations. The bulk properties of such planets are consistent with a range of pos…
Exploring the Sub-Neptune Frontier with JWST
Nikku Madhusudhan, Måns Holmberg, Savvas Constantinou +1
Sub-Neptune planets, with sizes and masses between those of Earth and Neptune, dominate the exoplanet population. Sub-Neptunes are expected to be the most diverse family of the exo…
New Constraints on DMS and DMDS in the Atmosphere of K2-18 b from JWST MIRI
Nikku Madhusudhan, Savvas Constantinou, Måns Holmberg +3
The sub-Neptune frontier has opened a new window into the rich diversity of planetary environments beyond the solar system. The possibility of hycean worlds, with planet-wide ocean…
Exoplanet Transit Spectroscopy with JWST NIRSpec: Diagnostics and Homogeneous Case Study of WASP-39 b
