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…
Confirmation of the hot super-Neptune TOI-672 b with NIRPS and HARPS and Insights into the Neptunian desert around M dwarfs
Ares Osborn, Ryan Cloutier, Vincent Bourrier +65
The Neptunian desert is a distinct lack of Neptune-sized planets at short orbital periods, purportedly carved by photoevaporation and tidal circularization following high-eccentric…
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…
The RoPES project with HARPS and HARPS-N II. A third planet in the multi-planet system HD 176986
N. Nari, A. Suárez Mascareño, J. I. González Hernández +7
Earth-like planets orbiting in the habitable zone of K- to G-type stars create an RV effect in amplitude of less than 1 \si{\meter\per\second} and have orbital periods of hundreds…
TOI-3288 b and TOI-4666 b: two gas giants transiting low-mass stars characterised by NIRPS
Yolanda G. C. Frensch, François Bouchy, Gaspare Lo Curto +62
Gas giant planets orbiting low-mass stars are uncommon outcomes of planet formation. Increasing the sample of well-characterised giants around early M dwarfs will enable population…
Diving into the planetary system of Proxima with NIRPS -- Breaking the metre per second barrier in the infrared
Alejandro Suárez Mascareño, Étienne Artigau, Lucile Mignon +138
We obtained 420 high-resolution spectra of Proxima, over 159 nights, using the Near Infra Red Planet Searcher (NIRPS). We derived 149 nightly binned radial velocity measurements wi…
