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…

The GRAVITY young stellar object survey -- XV. The star-disk interaction region of the T Tauri star DO Tau

GRAVITY Collaboration, K. Perraut, J. Bouvier +61

Protoplanetary disks around young Sun-like stars are the cradles of the vast majority of detected exoplanets. Probing these disks at multiple spatial scales is key to uncovering ho…

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…

Six-yr SPIRou monitoring of the young planet-host dwarf AU Mic

J. -F. Donati, P. I. Cristofari, C. Moutou +10

In this paper we revisit our spectropolarimetric and velocimetric analysis of the young M dwarf AU Mic based on data collected with SPIRou at the Canada-France-Hawaii telescope, ov…

SPIRou spectropolarimetry of the T Tauri star TW Hydrae: magnetic fields, accretion and planets

J. -F. Donati, P. I. Cristofari, L. T. Lehmann +15

In this paper we report near-infrared observations of the classical T Tauri star TW Hya with the SPIRou high-resolution spectropolarimeter and velocimeter at the 3.6-m Canada-Franc…
