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…
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…
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…
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…
Probing atmospheric escape through metastable He I triplet lines in 15 exoplanets observed with SPIRou
A. Masson, S. Vinatier, B. Bézard +23
For several years, the metastable helium triplet line has been successfully used as a tracer to probe atmospheric escape in transiting exoplanets. This absorption in the near-infra…
SPIRou spectropolarimetry of the T Tauri star TW Hydrae: magnetic fields, accretion and planets
J. -F. Donati, P. I. Cristofari, L. T. Lehmann +15
In this paper we report near-infrared observations of the classical T Tauri star TW Hya with the SPIRou high-resolution spectropolarimeter and velocimeter at the 3.6-m Canada-Franc…
Long-term monitoring of large-scale magnetic fields across optical and near-infrared domains with ESPaDOnS, Narval and SPIRou. The cases of EV Lac, DS Leo, and CN Leo
S. Bellotti, J. Morin, L. T. Lehmann +18
Dynamo models of stellar magnetic fields for partly and fully convective stars are guided by observational constraints. Zeeman-Doppler imaging has revealed a variety of magnetic fi…
