A Fourth Planet in the Kepler-51 System Revealed by Transit Timing Variations

Kento Masuda, Jessica E. Libby-Roberts, John H. Livingston +49

Kepler-51 is a -old Sun-like star hosting three transiting planets with radii - and orbital periods -$130\,\mathrm{day…

A Benchmark JWST Near-Infrared Spectrum for the Exoplanet WASP-39b

A. L. Carter, E. M. May, N. Espinoza +77

Observing exoplanets through transmission spectroscopy supplies detailed information on their atmospheric composition, physics, and chemistry. Prior to JWST, these observations wer…

New insights into the internal structure of GJ 1214 b informed by JWST

Matthew C. Nixon, Anjali A. A. Piette, Eliza M. -R. Kempton +7

Recent JWST observations of the sub-Neptune GJ 1214 b suggest that it hosts a high-metallicity (>100x solar), hazy atmosphere. Emission spectra of the planet show molecular absorpt…

Sulphur dioxide in the mid-infrared transmission spectrum of WASP-39b

Diana Powell, Adina D. Feinstein, Elspeth K. H. Lee +70

The recent inference of sulphur dioxide (SO) in the atmosphere of the hot (1100 K), Saturn-mass exoplanet WASP-39b from near-infrared JWST observations suggests that phot…

Hydrogen sulfide and metal-enriched atmosphere for a Jupiter-mass exoplanet

Guangwei Fu, Luis Welbanks, Drake Deming +15

As the closest transiting hot Jupiter to Earth, HD 189733b has been the benchmark planet for atmospheric characterization. It has also been the anchor point for much of our theoret…

Simultaneous retrieval of orbital phase resolved JWST/MIRI emission spectra of the hot Jupiter WASP-43b: evidence of water, ammonia and carbon monoxide

Jingxuan Yang, Mark Hammond, Anjali A. A. Piette +14

Spectroscopic phase curves of hot Jupiters measure their emission spectra at multiple orbital phases, thus enabling detailed characterisation of their atmospheres. Precise constrai…

Debris Disks can Contaminate Mid-Infrared Exoplanet Spectra: Evidence for a Circumstellar Debris Disk around Exoplanet Host WASP-39

Laura Flagg, Alycia J. Weinberger, Taylor J. Bell +21

The signal from a transiting planet can be diluted by astrophysical contamination. In the case of circumstellar debris disks, this contamination could start in the mid-infrared and…

Two-Dimensional Eclipse Mapping of the Hot Jupiter WASP-43b with JWST MIRI/LRS

Mark Hammond, Taylor J. Bell, Ryan C. Challener +21

We present eclipse maps of the two-dimensional thermal emission from the dayside of the hot Jupiter WASP-43b, derived from an observation of a phase curve with the JWST MIRI/LRS in…

Nightside clouds and disequilibrium chemistry on the hot Jupiter WASP-43b

Taylor J. Bell, Nicolas Crouzet, Patricio E. Cubillos +80

Hot Jupiters are among the best-studied exoplanets, but it is still poorly understood how their chemical composition and cloud properties vary with longitude. Theoretical models pr…
