Magnetic geometry of M dwarfs in the southern PLATO field
M. Diez, P. I. Cristofari, J. Morin +9
M dwarfs are the most abundant stars in the Galaxy and exhibit diverse magnetic behaviours. Understanding their large-scale magnetic fields is essential to study stellar dynamos an…
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…
Spectropolarimetric characterisation of exoplanet host stars in preparation of the Ariel mission. Magnetic environment of HD 63433
S. Bellotti, D. Evensberget, A. A. Vidotto +8
The accurate characterisation of the stellar magnetism of planetary host stars has been gaining momentum, especially in the context of transmission spectroscopy investigations of e…
Long-term monitoring of large-scale magnetic fields across optical and near-infrared domains with ESPaDOnS, Narval and SPIRou. The cases of EV Lac, DS Leo, and CN Leo
S. Bellotti, J. Morin, L. T. Lehmann +18
Dynamo models of stellar magnetic fields for partly and fully convective stars are guided by observational constraints. Zeeman-Doppler imaging has revealed a variety of magnetic fi…
Multi-scale magnetic field investigation of the M-dwarf eclipsing binary CU Cancri
A. Hahlin, O. Kochukhov, A. D. Rains +4
We aim to characterise the magnetic field of the eclipsing binary CU Cnc. The determination of magnetic field parameters of this target enables comparisons with both observations o…
The large-scale magnetic field of the M dwarf double-line spectroscopic binary FK Aqr
S. Tsvetkova, J. Morin, C. P. Folsom +10
This work is part of the BinaMIcS project, the aim of which is to understand the interaction between binarity and magnetism in close binary systems. All the studied spectroscopic b…
