Measuring small-scale magnetic fields of 44 M dwarfs from SPIRou spectra with ZeeTurbo

P. I. Cristofari, J. -F. Donati, C. Moutou +11

We present the results of an analysis aimed at probing the small-scale magnetic fields of M dwarfs observed with SPIRou, the nIR high-resolution spectro-polarimeter installed at th…

Monitoring the young planet host V1298 Tau with SPIRou: planetary system and evolving large-scale magnetic field

B. Finociety, J. -F. Donati, P. I. Cristofari +15

We report results of a spectropolarimetric monitoring of the young Sun-like star V1298~Tau based on data collected with the near-infrared spectropolarimeter SPIRou at the Canada-Fr…

Near-IR and optical radial velocities of the active M dwarf star Gl 388 (AD Leo) with SPIRou at CFHT and SOPHIE at OHP: A 2.23 day rotation period and no evidence for a corotating planet

A. Carmona, X. Delfosse, S. Bellotti +36

Context: The search for extrasolar planets around the nearest M dwarfs is a crucial step towards identifying the nearest Earth-like planets. One of the main challenges in this sear…

Optical and near-infrared stellar activity characterization of the early M dwarf Gl~205 with SOPHIE and SPIRou

P. Cortes-Zuleta, I. Boisse, B. Klein +41

The stellar activity of M dwarfs is the main limitation for discovering and characterizing exoplanets orbiting them since it induces quasi-periodic RV variations. We aim to charact…
