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…
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…
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…
GPI+SPHERE detection of a 6.1 circumbinary planet around HD 143811
Vito Squicciarini, Johan Mazoyer, Christian Wilkinson +6
Owing to its sensitivity to wide-orbit giant exoplanets, direct imaging is uniquely positioned to shed light on the interplay between protoplanetary disks and stellar hosts. In add…
