Unstable magnetospheric accretion on the T Tauri star TW Hya
J. -F. Donati, P. I. Cristofari, C. Moutou +9
The paper presents new spectropolarimetric and velocimetric observations of the T Tauri star TW Hya, revealing year‑scale variations in its large‑scale magnetic dipole and unstable…
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…
Searching for close-in planets around TWA 7 with SPIRou
J. -F. Donati, P. I. Cristofari, C. Moutou +7
We outline in this paper observations of the young pre-main-sequence low-mass star TWA 7, hosting a debris disk and a distant planet. Using data collected with the near-infrared SP…
SPIRou observations of the young planet-hosting star PDS 70
J. -F. Donati, P. I. Cristofari, S. H. P. Alencar +14
This paper presents near-infrared spectropolarimetric and velocimetric observations of the young planet-hosting T Tauri star PDS 70, collected with SPIRou at the 3.6m Canada-France…
