The circumstellar environment of the young, low-mass dipper star JH 223. Accretion and large-scale magnetic field topology
T. P. Freitas, J. Bouvier, B. Zaire +11
Studies of magnetospheric accretion and magnetic field topology in T Tauri stars have advanced over the years, but their applications to fully convective, very-low-mass T Tauri sta…
Activity correlation and temporal variation of small-scale magnetic fields on young Sun-like stars
A. Hahlin, B. Zaire, C. P. Folsom +2
We aim to evaluate how well the variation of small-scale magnetic fields on the stellar surface can be monitored with time-series observations. Further, we aim to establish to what…
SpecpolFlow: a new software package for spectropolarimetry using Python
Colin P. Folsom, Christiana Erba, Veronique Petit +8
Spectropolarimetry, the observation of polarization and intensity as a function of wavelength, is a powerful tool in stellar astrophysics. It is particularly useful for characteriz…
Magnetic field, magnetospheric accretion and candidate planet of the young star GM Aurigae observed with SPIRou
B. Zaire, J. -F. Donati, S. P. Alencar +13
This paper analyses spectropolarimetric observations of the classical T Tauri star (CTTS) GM Aurigae collected with SPIRou, the near-infrared spectropolarimeter at the Canada-Franc…
Star-disk interactions in the strongly accreting T Tauri Star S CrA N
H. Nowacki, E. Alecian, K. Perraut +11
Aims : We aimed at constraining the accretion-ejection phenomena around the strongly-accreting Northern component of the S CrA young binary system (S CrA N) by deriving its magneti…
The SPIRou Legacy Survey Rotation period of quiet M dwarfs from circular polarization in near-infrared spectral lines: I. The SPIRou APERO analysis
P. Fouqué, E. Martioli, J. -F. Donati +21
Context. The rotation period of stars is an important parameter along with mass, radius, effective temperature. It is an essential parameter for any radial velocity monitoring, as…
