On the reliability of mass-loss-rate estimates for AGB stars

Context. In the recent literature there has been some doubt as to the reliability of CO multi-transitional line observations as a mass-loss-rate estimator for AGB stars. Aims. Using new well-calibr

Circumstellar water vapour in M-type AGB stars: constraints from H2O(110-101) lines obtained with Odin

Context. A detailed radiative transfer code has been previously used to model circumstellar ortho-H2O line emission towards six M-type asymptotic giant branch stars using Infrared Space Observatory

Probing chemical processes in AGB stars

Abstract We are conducting multi-transition observations of circumstellar line emission from common molecules such as HCN, SiO, CS, SiS and CN for a large sample of AGB stars with varying

A circumstellar journey—physics and chemistry of AGB stellar winds

The physics and chemistry of the envelopes of gas and dust that surround stars on the asymptotic giant branch are the subjects of this review. Estimates of stellar mass-loss rates in this phase, as

Winds of AGB stars: does size matter?

Asymptotic giant branch (AGB) stars are showing clear signs of significant mass loss through cool stellar winds. These outflows are attributed to the combined effects of pulsation-induced shocks and

Detailed modelling of the circumstellar molecular line emission of the S-type AGB star W Aquilae

Context. S-type AGB stars have a C/O ratio which suggests that they are transition objects between oxygen-rich M-type stars and carbon-rich C-type stars. As such, their circumstellar compositions of

Probing the mass-loss history of AGB and red supergiant stars from CO rotational line profiles. II. CO line survey of evolved stars: derivation of mass-loss rate formulae

Context. The evolution of intermediate and low-mass stars on the asymptotic giant branch is dominated by their strong dust-driven winds. More massive stars evolve into red supergiants with a similar

Infrared photometry and evolution of mass-losing AGB stars. III. Mass loss rates of MS and S stars

Context. The asymptotic giant branch (AGB) phase marks the end of the evolution for low- and intermediate-mass stars, which are fundamental contributors to the mass return to the inter stellar medium

A chemical inventory of the S-type AGB star χ Cygni based on Herschel/HIFI observations of circumstellar line emission. The importance of non-LTE chemical processes in a dynamical region

Context. S-type AGB stars (C/O ≈ 1) are thought to be transition objects from M-type (O-rich) AGB stars to carbon stars and as such are interesting objects in themselves. Of particular interest is to

The abundance of HCN in circumstellar envelopes of AGB stars of different chemical type

Aims. A multi-transition survey of HCN (sub-) millimeter line emission from a large sample of asymptotic giant branch (AGB) stars of different chemical type is presented. The data are analysed and



Probing the Mass Loss Rate History of Carbon Stars Using CO Line and Dust Continuum Emission

We have modelled radio and far-infrared rotational lines of (CO)-C-12 and (CO)-C-13 Obtained from the circumstellar envelope of the infrared-bright carbon star IRAS 15194-5115. Eleven rotational

Models of circumstellar molecular radio line emission - Mass loss rates for a sample of bright carbon stars

Using a detailed radiative transfer analysis, combined with an energy balance equation for the gas, we have performed extensive modelling of circumstellar CO radio line emission from a large sample

High-mass-loss AGB Stars in the South Galactic Cap

Observations are presented for 61 Miras in the South Galactic Cap (b<−30°) which were selected on the basis of their IRAS 12/25-μm flux ratios as high-mass-loss candidates. JHKL photometry (over 1

Mass loss from S stars

The mass-loss process in S stars is studied using 65 S stars from the listing of Wing and Yorka (1977). The role of pulsations in the mass-loss process is examined. It is detected that stars with
