Rotational modulation and long-term evolution of the small-scale magnetic fields of M dwarfs observed with SPIRou
P. I. Cristofari, J. -F. Donati, S. Bellotti +7
M dwarfs are known to host magnetic fields, impacting exoplanet studies and playing a key role in stellar and planetary formation and evolution. Observations revealed the long-term…
Full Stokes magnetometry of the active M dwarfs AU Mic and EV Lac with SPIRou
J. -F. Donati, P. I. Cristofari, B. Klein +2
We report in this paper circularly and linearly polarized observations of the young active M dwarfs AU Mic and EV Lac with the near-infrared SPIRou spectropolarimeter at the Canada…
The classical T Tauri star CI Tau observed with SPIRou: magnetospheric accretion and planetary formation
J. -F. Donati, B. Finociety, P. I. Cristofari +15
We report new observations of the classical T~Tauri star CI~Tau with the SPIRou near-infrared spectropolarimeter and velocimeter at the Canada-France-Hawaii Telescope (CFHT) in lat…
The magnetic field and multiple planets of the young dwarf AU~Mic
J. -F. Donati, P. I. Cristofari, B. Finociety +25
In this paper we present an analysis of near-infrared spectropolarimetric and velocimetric data of the young M dwarf AU Mic, collected with SPIRou at the Canada-France-Hawaii teles…
Mapping time-dependent magnetic topologies of active stars
Benjamin Finociety, Jean-François Donati
Throughout the last decades, Zeeman-Doppler Imaging (ZDI) has been intensively used to reconstruct large-scale magnetic topologies of active stars from time series of circularly po…
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…
