HI line observations of 290 evolved stars made with the Nancay Radio Telescope -- I. Data
E. Gerard, W. van Driel, L. D. Matthews +3
We present a compendium of HI 21-cm line observations of circumstellar envelopes (CSEs) of 290 evolved stars, mostly (~84%) on the asymptotic giant branch (AGB), made with the 100m…
The multi-scale environment of RS Cnc from CO and HI observations
D. T. Hoai, L. D. Matthews, J. M. Winters +4
We present a detailed study of the circumstellar gas distribution and kinematics of the semi-regular variable star RS Cnc on spatial scales ranging from ~1" (~150 AU) to ~6' (~0.25…
Discovery of a detached HI gas shell surrounding alpha Orionis
T. Le Bertre, L. D. Matthews, E. Gérard +1
We report the detection of the HI line at 21 cm in the direction of alpha Ori with the Nancay Radiotelescope and with the Very Large Array. The observations confirm the previous de…
Circumstellar HI and CO around the carbon stars V1942 Sgr and V CrB
Y. Libert, E. Gerard, C. Thum +3
Context. The majority of stars that leave the main sequence are undergoing extensive mass loss, in particular during the asymptotic giant branch (AGB) phase of evolution. Observati…
HI in circumstellar environments
Gerard, Le Bertre
We present new results of a spectroscopic survey of circumstellar HI in the direction of evolved stars made with the Nancay Radiotelescope. The HI line at 21 cm has been detected i…
