ALMA observations of the nearby AGB star L2 Puppis - I. Mass of the central star and detection of a candidate planet
P. Kervella, W. Homan, A. M. S. Richards +4
Six billion years from now, while evolving on the asymptotic giant branch (AGB), the Sun will metamorphose from a red giant into a beautiful planetary nebula. This spectacular evol…
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…
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…
