Spectropolarimetric characterisation of exoplanet host stars in preparation of the mission II. The magnetised wind environment of TOI-1860, DS Tuc A, and HD 63433
S. Bellotti, A. Lavail, D. Evensberget +10
We update the status of the spectropolarimetric campaign dedicated to characterise the magnetic field properties of a sample of known exoplanet-hosting stars included in the curren…
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…
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…
The magnetic and spin-down properties of slowly rotating fully convective M dwarfs
Victor See, Louis Amard, Stefano Bellotti +19
The evolution of the magnetism, winds and rotation of low-mass stars are all linked. One of the most common ways to probe the magnetic properties of low-mass stars is with the Zeem…
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…
