NIRPS detection of delayed atmospheric escape from the warm and misaligned Saturn-mass exoplanet WASP-69b

Romain Allart, Yann Carteret, Vincent Bourrier +119

Near-infrared high-resolution echelle spectrographs unlock access to fundamental properties of exoplanets, from their atmospheric escape and composition to their orbital architectu…

Hydride ion continuum hides absorption signatures in the NIRPS near-infrared transmission spectrum of the ultra-hot gas giant WASP-189b

Valentina Vaulato, Stefan Pelletier, David Ehrenreich +77

Ultra-hot Jupiters showcase extreme atmospheric conditions, including molecular dissociation, ionisation, and significant day-to-night temperature contrasts. Their close proximity…

JWST Reveals CH, CO, and HO in a Metal-rich Miscible Atmosphere on a Two-Earth-Radius Exoplanet

Björn Benneke, Pierre-Alexis Roy, Louis-Philippe Coulombe +28

Even though sub-Neptunes likely represent the most common outcome of planet formation, their natures remain poorly understood. In particular, planets near 1.5-2.5 often…

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…

Characterizing the Near-infrared Spectra of Flares from TRAPPIST-1 During JWST Transit Spectroscopy Observations

Ward S. Howard, Adam F. Kowalski, Laura Flagg +16

We present the first analysis of JWST near-infrared spectroscopy of stellar flares from TRAPPIST-1 during transits of rocky exoplanets. Four flares were observed from 0.6--2.8 m…

A roadmap for the atmospheric characterization of terrestrial exoplanets with JWST

TRAPPIST-1 JWST Community Initiative, :, Julien de Wit +80

Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominen…
