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…
Planetary-Mass Exosatellite Detected Around the Substellar Companion of a Star
Kevin Hoy, Alice Zurlo, Pablo A. Peña R. +10
Despite more than 6000 exoplanets being discovered to date, no satellite orbiting an exoplanet, an exomoon, has ever been confidently detected. While there are some candidates, the…
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…
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…
