Next-generation Exo-REM atmospheric models: application to VHS 1256 b to emulate patchy clouds

Alice Radcliffe, Benjamin Charnay, Anne-Marie Lagrange +7

Condensate clouds are a defining feature of brown dwarf and exoplanet atmospheres, producing a broad range of colours on the CMD and giving rise to spectral features such as the di…

Searching for Molecular Signatures in 14 Transiting Exoplanets with SPIRou

A. Masson, S. Vinatier, B. Bézard +6

High-resolution spectroscopy provides unique constraints on exoplanet atmospheric composition and dynamics. The past decade of ground-based campaigns has accumulated extensive publ…

X-SHYNE: X-Shooter spectra of young exoplanet analogs II. Presentation and analysis of the full library

Simon Petrus, Gaël Chauvin, Mickaël Bonnefoy +29

The X-SHYNE library is a homogeneous sample of 43 medium-resolution (R=8000) infrared (0.3-2.5um) spectra of young (<500Myr), low-mass (<20Mjup), and cold (Teff=600-2000K) isolated…

Probing atmospheric escape through metastable He I triplet lines in 15 exoplanets observed with SPIRou

A. Masson, S. Vinatier, B. Bézard +23

For several years, the metastable helium triplet line has been successfully used as a tracer to probe atmospheric escape in transiting exoplanets. This absorption in the near-infra…

A new treatment of telluric and stellar features for medium resolution spectroscopy and molecular mapping. Application to the abundance determination on Beta Pic b

F. Kiefer, M. Bonnefoy, B. Charnay +5

Molecular mapping is a supervised method exploiting the spectral diversity of integral field spectrographs to detect and characterize resolved exoplanets blurred into the stellar h…

The radiative and dynamical impact of clouds in the atmosphere of the hot Jupiter WASP-43 b

Lucas Teinturier, Benjamin Charnay, Aymeric Spiga +6

Hot Jupiters exhibit large day-night temperature contrasts. Their cooler nightsides are thought to host clouds. However, the exact nature of these clouds, their spatial distributio…
