ForMoSA: Forward Modeling tool for Spectral Analysis
ForMoSA Collaboration, Simon Petrus, Paulina Palma-Bifani +9
ForMoSA is an open‑source Python package that uses Bayesian methods to fit spectroscopic and photometric data of directly imaged young planetary‑mass brown dwarfs and exoplanets, s…
Latitudinal chemical and cloud variations in the atmosphere of a brown dwarf
Benjamin Charnay, Sam de Regt, Matthieu Ravet +8
The paper introduces a technique called Differential Molecular Rotational Broadening to detect latitudinal chemical differences in brown dwarf atmospheres, and applies it to VLT-CR…
Panchromatic View of the Frigid Jovian Exoplanet COCONUTS-2 b
Matthieu Ravet, Mickaël Bonnefoy, Gaël Chauvin +24
We use a high signal-to-noise MIRI-LRS spectrum (5.45 - 11 m, R ) of COCONUTS-2~b revealing prominent molecular features of HO, CH and NH. This datase…
Cold and eccentric: a high-spectral resolution view of 51 Eri b with VLT/HiRISE
A. Denis, A. Vigan, G. Chauvin +35
Discovered almost 10 years ago, the giant planet 51 Eridani b is one of the least separated (0.2 arcsec) and faintest (J = 19.74 mag) directly imaged exoplanets known to date. Its…
Multi-modal atmospheric characterization of Pictoris b: Adding high-resolution continuum spectra from GRAVITY
M. Ravet, M. Bonnefoy, G. Chauvin +24
We present the first VLTI/GRAVITY observations at R of Pic b. These four high S/N (20) K-band spectra conserve both the pseudo-continuum and molecular abso…
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…
