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…
Testing the validity of the ray-tracing code GYOTO
Marion Grould, Thibaut Paumard, Guy Perrin
In the next few years, the near-infrared interferometer GRAVITY will be able to observe the Galactic center. Astrometric data will be obtained with an anticipated accuracy of 10 $μ…
The close circumstellar environment of Betelgeuse. IV. VLTI/PIONIER interferometric monitoring of the photosphere
M. Montargès, P. Kervella, G. Perrin +9
Context. The mass-loss mechanism of cool massive evolved stars is poorly understood. The proximity of Betelgeuse makes it an appealing target to study its atmosphere, map the shape…
