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…
First images of Antares photosphere from spectropolarimetry
Quentin Pilate, Eric Josselin, Agnès Lèbre +3
Antares is the closest red supergiant (RSG) to Earth. The discovery of linear polarization in the atomic lines of the star opens the path to produce direct images of the photospher…
The variability of Betelgeuse explained by surface convection
Quentin Pilate, Arturo López Ariste, Alexis Lavail +1
Context. Betelgeuse is a red supergiant (RSG) that is known to vary semi-regularly on both short and long timescales. The origin of the short period of Betelgeuse has often been as…
SiO maser polarization and magnetic field in evolved cool stars
L. Marinho, F. Herpin, H. Wiesemeyer +6
Both magnetic fields and photospheric/atmospheric dynamics can be involved in triggering the important mass loss observed in evolved cool stars. Previous works have revealed that t…
The height of convective plumes in the red supergiant Cep
A. López Ariste, M. Wavasseur, Ph. Mathias +3
Aims. We seek to understand convection in red supergiants and the mechanisms that trigger the mass loss from cool evolved stars. Methods. Linear spectropolarimetry of the atomic li…
