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…
Radiation-pressure-driven sub-Keplerian rotation of the disc around the AGB star L2 Pup
Thomas J. Haworth, Richard A. Booth, Ward Homan +3
We study the sub-Keplerian rotation and dust content of the circumstellar material around the asymptotic giant branch (AGB) star L Puppis. We find that the thermal pressure gra…
Chemical content of the circumstellar envelope of the oxygen-rich AGB star R Dor: Non-LTE abundance analysis of CO, SiO, and HCN
M. Van de Sande, L. Decin, R. Lombaert +5
(abridged) Our aim is to determine the radial abundance profile of SiO and HCN throughout the stellar outflow of R Dor, an oxygen-rich AGB star with a low mass-loss rate. We have a…
