Upside down: GJ3090 b the first retrograde exoplanet around an M dwarf detected with NIRPS
Y. Carteret, V. Bourrier, L. Parc +57
The angle between stellar spin axis and planetary orbital plane can provide key insights into the formation and dynamical evolution of planetary systems. In particular, this measur…
Radial velocity detection of the TRAPPIST-1 planetary system with SPIRou and NIRPS
Alexandrine L'Heureux, René Doyon, Charles Cadieux +57
The TRAPPIST-1 system is well-known for its seven transiting Earth-sized exoplanets. It has been extensively studied and characterized, notably with transit timing variations (TTVs…
Mass constraints for the K2-223 system planets: An ultra-short-period sub-Earth, a short-period super-Earth, and a tentative long-period giant planet
Dawid Jankowski, Grzegorz Nowak, Gaia Lacedelli +23
We present mass constraints of two short-period Earth-sized planets transiting K2-223 based on high-precision radial velocity measurements from HARPS-N and ESPRESSO, as well as a t…
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…
The RoPES project with HARPS and HARPS-N III. Two candidate planets orbiting the G-type star HD 161098
N. Nari, A. Suárez Mascareño, J. I. González Hernández +9
Context. The development of refined instruments and techniques for a detailed analysis of the radial velocities (RVs) of stars other than the Sun allows the presence of planetary 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…
