Characterisation of TOI-406 as showcase of the THIRSTEE program: A 2-planet system straddling the M-dwarf density gap

G. Lacedelli, E. Pallè, R. Luque +31

The exoplanet sub-Neptune population currently poses a conundrum, as to whether small-size planets are volatile-rich cores without an atmosphere, or rocky cores surrounded by a H-H…

Gl 725A b: a potential super-Earth detected with SOPHIE and SPIRou in an M dwarf binary system at 3.5 pc

P. Cortes-Zuleta, I. Boisse, M. Ould-Elhkim +34

We report the discovery of a super-Earth candidate orbiting the nearby mid M dwarf Gl\,725A using the radial velocity (RV) method. The planetary signal has been independently ident…

SPIRou observations of the young planet-hosting star PDS 70

J. -F. Donati, P. I. Cristofari, S. H. P. Alencar +14

This paper presents near-infrared spectropolarimetric and velocimetric observations of the young planet-hosting T Tauri star PDS 70, collected with SPIRou at the 3.6m Canada-France…

TOI-3568 b: a super-Neptune in the sub-Jovian desert

E. Martioli, R. P. Petrucci, E. Jofre +42

The sub-Jovian desert is a region in the mass-period and radius-period parameter space, typically encompassing short-period ranges between super-Earths and hot Jupiters, that exhib…

ANDES, the high resolution spectrograph for the ELT: science goals, project overview and future developments

A. Marconi, M. Abreu, V. Adibekyan +286

The first generation of ELT instruments includes an optical-infrared high-resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion E…

Characterizing planetary systems with SPIRou: a temperate sub-Neptune exoplanet orbiting the nearby fully-convective star GJ 1289 and a candidate around GJ 3378

C. Moutou, M. Ould-Elhkim, J. -F. Donati +12

We report the discovery of two new exoplanet systems around fully convective stars, found from the radial-velocity (RV) variations of their host stars measured with the nIR spectro…
