Confirming the Magnetic Field Detection at the Surface of Cyg
Alexis Lavail, Arturo López Ariste, Quentin Pilate +3
We present spectropolarimetric observations of Cygni obtained with Neo-Narval at Télescope Bernard Lyot in 2025. We obtained observations across three epochs (2025 Jul, Aug, an…
Atomium: The astounding complexity of the near circumstellar environment of the M-type AGB star R Hydrae. I. Morpho-kinematical interpretation of CO and SiO emission
Ward Homan, Bannawit Pimpanuwat, Fabrice Herpin +36
Evolved low- to intermediate-mass stars are known to shed their gaseous envelope into a large, dusty, molecule-rich circumstellar nebula which typically develops a high degree of s…
Atomium: A high-resolution view on the highly asymmetric wind of the AGB star Pi1 Gruis. I. First detection of a new companion and its effect on the inner wind
Ward Homan, Miguel Montarges, Bannawit Pimpanuwat +35
The nebular circumstellar environments of cool evolved stars are known to harbour a rich morphological complexity of gaseous structures on different length scales. A large part of…
(Sub)stellar companions shape the winds of evolved stars
L. Decin, M. Montargès, A. M. S. Richards +32
Binary interactions dominate the evolution of massive stars, but their role is less clear for low- and intermediate-mass stars. The evolution of a spherical wind from an asymptotic…
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…
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…
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…
Search for surface magnetic fields in Mira stars. First detection in chi Cyg
A. Lèbre, M. Aurière, N. Fabas +4
In order to complete the knowledge of the magnetic field and of its influence during the transition from Asymptotic Giant Branch to Planetary Nebulae stages, we have undertaken a s…
