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…
Rotational modulation and long-term evolution of the small-scale magnetic fields of M dwarfs observed with SPIRou
P. I. Cristofari, J. -F. Donati, S. Bellotti +7
M dwarfs are known to host magnetic fields, impacting exoplanet studies and playing a key role in stellar and planetary formation and evolution. Observations revealed the long-term…
Full Stokes magnetometry of the active M dwarfs AU Mic and EV Lac with SPIRou
J. -F. Donati, P. I. Cristofari, B. Klein +2
We report in this paper circularly and linearly polarized observations of the young active M dwarfs AU Mic and EV Lac with the near-infrared SPIRou spectropolarimeter at the Canada…
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…
Mass, Gas, and Gauss around a T Tauri Star with SPIRou
J. -F. Donati, E. Gaidos, C. Moutou +4
Studies of young planets help us understand planet evolution and investigate important evolutionary processes such as atmospheric escape. We monitored IRAS 04125+2902, a 3 Myr-old…
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…
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…
Monitoring the large-scale magnetic field of AD~Leo with SPIRou, ESPaDOnS and Narval. Toward a magnetic polarity reversal?
S. Bellotti, J. Morin, L. T. Lehmann +23
One manifestation of dynamo action on the Sun is the 22-yr magnetic cycle, exhibiting a polarity reversal and a periodic conversion between poloidal and toroidal fields. For M dwar…
