MELCHIORS: The Mercator Library of High Resolution Stellar Spectroscopy
P. Royer, T. Merle, K. Dsilva +71
Over the past decades, libraries of stellar spectra have been used in a large variety of science cases, including as sources of reference spectra for a given object or a given spec…
PACS and SPIRE range spectroscopy of cool, evolved stars
Dries Nicolaes, M. A. T. Groenewegen, P. Royer +3
Context: At the end of their lives AGB stars are prolific producers of dust and gas. The details of this mass-loss process are still not understood very well. Herschel PACS and SPI…
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…
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…
ALMA observations of the vibrationally-excited rotational CO transition towards five AGB stars
T. Khouri, W. H. T. Vlemmings, S. Ramstedt +3
We report the serendipitous detection with ALMA of the vibrationally-excited pure-rotational CO transition towards five asymptotic giant branch (AGB) stars, Cet, R…
Nucleosynthesis in AGB stars traced by oxygen isotopic ratios. I - Determining the stellar initial mass by means of the O/O ratio
R. De Nutte, L. Decin, H. Olofsson +8
The aim of this paper is to investigate the O/O ratio for a sample of AGB stars, containing M-, S- and C-type stars. These ratios are evaluated in relation to fundame…
