Surface magnetism in the pulsating RV Tauri star R Scuti
Stefan Georgiev, Agnès Lèbre, Eric Josselin +3
We present the surface magnetic field conditions of the brightest pulsating RV Tauri star, R Sct. Our investigation is based on the longest spectropolarimetric survey ever performe…
Pollux: A weak dynamo-driven dipolar magnetic field and implications for its probable planet
M. Aurière, P. Petit, P. Mathias +7
Context: Pollux is considered as an archetype of a giant star hosting a planet. We then discovered a weak magnetic field at its surface using spectropolarimetry. Aims and Methods:…
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.…
CRIRES high-resolution infrared spectroscopy of the long-period Cepheid l Car
N. Nardetto, E. Poretti, A. Gallenne +17
The dynamical structure of the atmosphere of Cepheids has been well studied in the optical. Several authors have found very interesting spectral features in the J band, but little…
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…
