Magnetic field measurements in a sample of Class I and flat-spectrum protostars observed with SPIRou

L. Drouglazet, E. Alecian, A. Sousa +27

Magnetic fields play a crucial role throughout stellar evolution, regulating angular momentum, channelling accretion, and launching jets and outflows. While the magnetic properties…

Monitoring the magnetospheric accretion of the classical T Tauri star DO Tau with SPIRou

J. -F. Donati, P. I. Cristofari, A. Carmona +11

We present observations of the classical T Tauri star DO Tau collected with the near-infrared SPIRou spectropolarimeter and precision velocimeter at the Canada-France-Hawaii Telesc…

Evolving magnetic lives of Sun-like stars. I. Characterisation of the large-scale magnetic field with Zeeman-Doppler imaging

S. Bellotti, T. Lueftinger, S. Boro Saikia +6

Planets orbiting young, solar-type stars are embedded in a more energetic environment than that of the solar neighbourhood. They experience harsher conditions due to enhanced stell…

HD 34736: An intensely magnetised double-lined spectroscopic binary with rapidly-rotating chemically peculiar B-type components

E. Semenko, O. Kochukhov, Z. Mikulášek +21

We report the results of a comprehensive study of the spectroscopic binary (SB2) system HD 34736 hosting two chemically peculiar (CP) late B-type stars. Using new and archival obse…

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…

Coriolis darkening in late-type stars II. Effect of self-sustained magnetic fields in stratified convective envelope

C. Pinçon, L. Petitdemange, R. Raynaud +4

Modeling the surface brightness distribution of stars is of prime importance to interpret observations. Nevertheless, this remains quite challenging for cool stars as it requires o…
