History of two mass loss processes in VY CMa. Fast outflows carving older ejecta
G. Quintana-Lacaci, L. Velilla-Prieto, M. Agúndez +4
Red supergiant stars (RSGs, Minit = 10-40Msun) are known to eject large amounts of material, as much as half of their initial mass during this evolutionary phase. However, the proc…
Water isotopologues in the circumstellar envelopes of M-type AGB stars
Taïssa Danilovich, R. Lombaert, L. Decin +3
AIM: In this study we examine rotational emission lines of two isotopologues of water: HO and HO. By determining the abundances of these molecules, we aim to…
On the properties of dust and gas in the environs of V838 Monocerotis
K. M. Exter, N. L. J. Cox, B. M. Swinyard +4
Herschel FIR imaging and spectroscopy were taken at several epochs to probe the central point source and the extended environment of V838 Mon. PACS and SPIRE maps were used to obta…
Herschel/HIFI observations of the circumstellar ammonia lines in IRC+10216
M. R. Schmidt, J. H. He, R. Szczerba +14
New high-resolution far-infrared (FIR) observations of both ortho- and para-NH3 transitions toward IRC+10216 were obtained with Herschel, with the goal of determining the ammonia a…
Study of the inner dust envelope and stellar photosphere of the AGB star R Doradus using SPHERE/ZIMPOL
T. Khouri, M. Maercker, L. B. F. M. Waters +12
We use high-angular-resolution images obtained with SPHERE/ZIMPOL to study the photosphere, the warm molecular layer, and the inner wind of the close-by oxygen-rich AGB star R Dora…
Herschel observations of extreme OH/IR stars - the isotopic ratios of oxygen as a sign-post for the stellar mass
K. Justtanont, M. J. Barlow, J. Blommaert +10
Aim: The late stages of stellar evolution are mainly governed by the mass of the stars. Low- and intermediate-mass stars lose copious amounts of mass during the asymptotic giant br…
