Observation of narrow polar jets in the nascent wind of oxygen-rich AGB star EP Aqr
P. Tuan-Anh, D. T. Hoai, P. T. Nhung +6
Using ALMA observations of CO(2-1), SiO(5-4) and SO(16-17) emissions of the circumstellar envelope of AGB star EP Aqr, we describe the mo…
NOEMA maps the CO environment of the red supergiant Cep
M. Montargès, W. Homan, D. Keller +8
Red supergiant stars are surrounded by a gaseous and dusty circumstellar environment created by their mass loss which spreads heavy elements into the interstellar medium. The struc…
ALMA observations of the circumstellar envelope around EP Aqr
P. T. Nhung, D. T. Hoai, P. Tuan-Anh +6
Atacama Large Millimetre/sub-millimetre Array (ALMA) observations of the CO(1-0) and CO(2-1) emissions from the circumstellar envelope of the Asymptotic Giant Branch (AGB) star EP…
De-projection of radio observations of axi-symmetric expanding circumstellar envelopes
P. T. Nhung, D. T. Hoai, P. Tuan-Anh +5
The problem of de-projection of radio line observations of axi-symmetric expanding circumstellar envelopes is studied with the aim of easing their analysis in terms of physics mode…
Modeling the HI 21-cm line profile from circumstellar shells around red giants
Do Thi Hoai, Pham Thi Nhung, Eric Gérard +3
We present HI line profiles for various models of circumstellar shells around red giants. In the calculations we take into account the effect of the background at 21 cm, and show t…
Discovery of a Shell of Neutral Atomic Hydrogen Surrounding the Carbon Star IRC+10216
L. D. Matthews, E. Gerard, T. Le Bertre
We have used the Robert C. Byrd Green Bank Telescope to perform the most sensitive search to date for neutral atomic hydrogen (HI) in the circumstellar envelope (CSE) of the carbon…
