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…
Parametrizing the projected wind fields of ultra-hot Jupiters in thermal emission: an application to GCM spectra of WASP-76b
Joost P. Wardenier, Romain Allart, Georgia Mraz +5
High-resolution thermal emission spectroscopy provides a powerful probe of atmospheric circulation in ultra-hot Jupiters (UHJs), with Doppler shifts encoding information about the…
The breaking of cold traps and onset of titanium in ultra-hot Jupiter atmospheres: WASP-189b in context
Stefan Pelletier, Romain Allart, Valentina Vaulato +56
Condensates are ubiquitous to all Solar System planets with significant (10mbar) atmospheres. The same is true for most exoplanets with characterised atmospheres, with even ultr…
Towards Doppler eclipse mapping of hot Jupiters. An observational perspective on WASP-33 b with SPIRou
Vincent Yariv, Xavier Bonfils, Nicolas Cowan +7
In the last decade, ground-based high-resolution spectroscopy (HRS) has emerged as a powerful method to probe exoplanet atmospheres both in transit and thermal emission. With HRS s…
Super-Earth masses and stellar abundances from NIRPS reveal tentative evidence for water-rich formation around M dwarfs
Drew Weisserman, Nicole Gromek, Ryan Cloutier +98
Tracing the compositional link between terrestrial super-Earths and their host stars provides clues to their dominant formation pathway. By constraining the stellar abundances of r…
NIRPS tightens the mass estimate of GJ 3090 b and detects a planet near the stellar rotation period
Pierrot Lamontagne, Drew Weisserman, Charles Cadieux +148
We present an updated characterization of the planetary system orbiting the nearby M2 dwarf GJ 3090 (TOI-177; pc), based on new high-precision radial velocity (RV) observa…
