Constraining atmospheric parameters and surface magnetic fields with : an application to SPIRou spectra
P. I. Cristofari, J. -F. Donati, C. P. Folsom +8
We report first results on a method aimed at simultaneously characterising atmospheric parameters and magnetic properties of M dwarfs from high-resolution nIR spectra recorded with…
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…
Estimating the atmospheric properties of 44 M dwarfs from SPIRou spectra
P. I. Cristofari, J. -F. Donati, T. Masseron +8
We describe advances on a method designed to derive accurate parameters of M dwarfs. Our analysis consists in comparing high-resolution infrared spectra acquired with the near-infr…
The T Tauri star V410 Tau in the eyes of SPIRou and TESS
Benjamin Finociety, Jean-François Donati, Baptiste Klein +16
We report results of a spectropolarimetric and photometric monitoring of the weak-line T Tauri star V410 Tau based on data collected mostly with SPIRou, the near-infrared (NIR) spe…
Spin-orbit alignment and magnetic activity in the young planetary system AU Mic
E. Martioli, G. Hebrard, C. Moutou +21
We present high resolution near-infrared spectropolarimetric observations using the SPIRou instrument at CFHT during a transit of the recently detected young planet AU Mic b, with…
CRIRES high-resolution infrared spectroscopy of the long-period Cepheid l Car
N. Nardetto, E. Poretti, A. Gallenne +17
The dynamical structure of the atmosphere of Cepheids has been well studied in the optical. Several authors have found very interesting spectral features in the J band, but little…
