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…

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…

Electron Cyclotron Maser Emission from Ejected Stellar Prominences on V374 Peg

C. E. Brasseur, M. M. Jardine, S. Daley-Yates +2

We investigate a possible origin for bursty radio emission observed on the active M dwarf V374 Peg, combining data-driven magnetic field modelling with archival radio light curves.…

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…

Characterizing planetary systems with SPIRou: questions about the magnetic cycle of 55 Cnc A and two new planets around B

C. Moutou, P. Petit, P. Charpentier +12

One of the first exoplanet hosts discovered thirty years ago, the star 55 Cnc has been constantly observed ever since. It is now known to host at least five planets with orbital pe…
