Asymmetric shocks in Cyg observed with linear spectropolarimetry
A. López Ariste, B. Tessore, E. S. Carlín +7
Aims: From a coherent interpretation of the linear polarisation detected in the spectral lines of the Mira star Cyg, we derive information about the dynamics of the stellar pho…
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.…
Detection of the linearly polarised spectrum of the red supergiant star alpha Ori
Benjamin Tessore, Arturo Lòpez-Ariste, Philippe Mathias +3
In the solar limb, linear polarisation is due to anisotropy of the radiation field induced by limb darkening. It is maximal when it is seen parallel to the limb and it vanishes whe…
Discovery of a complex linearly polarized spectrum of Betelgeuse dominated by depolarization of the continuum
M. Aurière, A. López Ariste, P. Mathias +15
Betelgeuse is an M supergiant that harbors spots and giant granules at its surface and presents linear polarization of its continuum. We have previously discovered linear polarizat…
