Convective cells in Betelgeuse: imaging through spectropolarimetry
A. López Ariste, P. Mathias, B. Tessore +7
We assess the ability to image the photosphere of red supergiants and, in particular Betelgeuse, through the modelling of the observed linear polarization in atomic spectral lines.…

Evolution of the magnetic field of Betelgeuse from 2009 - 2017
P. Mathias, M. Aurière, A. López Ariste +14
Betelgeuse is an M-type supergiant that presents a circularly polarized (Stokes V) signal in its line profiles, interpreted in terms of a surface magnetic field. The weak circular…
