The SPHERE data center: a reference for high contrast imaging processing
Ph. Delorme, N. Meunier, D. Albert +19
The objective of the SPHERE Data Center is to optimize the scientific return of SPHERE at the VLT, by providing optimized reduction procedures, services to users and publicly avail…
The close circumstellar environment of Betelgeuse - V. Rotation velocity and molecular envelope properties from ALMA
Pierre Kervella, Leen Decin, Anita M. S. Richards +6
We observed Betelgeuse using ALMA's extended configuration in band 7 (f~340 GHz, λ~0.88 mm), resulting in a very high angular resolution of 18 mas. Using a solid body rotation mode…
The inhomogeneous sub-millimeter atmosphere of Betelgeuse
E. O'Gorman, P. Kervella, G. M. Harper +4
The mechanisms responsible for heating the extended atmospheres of early-M spectral-type supergiants are poorly understood. So too is the subsequent role these mechanisms play in d…
The convective surface of the red supergiant Antares. VLTI/PIONIER interferometry in the near infrared
M. Montargès, A. Chiavassa, P. Kervella +4
Context. Convection is a candidate to explain the trigger of red supergiant star mass loss. Owing to the small size of the convective cells on the photosphere, few of their charact…
Asymmetries on red giant branch surfaces from CHARA/MIRC optical interferometry
A. Chiavassa, R. Norris, M. Montargès +14
Context. Red giant branch (RGB) stars are very bright objects in galaxies and are often used as standard candles. Interferometry is the ideal tool to characterize the dynamics and…
