AGB stars of the intermediate-age LMC cluster NGC 1846 II. Dredge up along the AGB
T. Lebzelter, M. T. Lederer, S. Cristallo +3
Aims: We investigate the change in the surface abundance of C during the evolution along the AGB, aiming to constrain third dredge-up models. Methods: High-resolution, near-…
Long period variables in the globular cluster 47 Tuc: radial velocity variations
T. Lebzelter, P. R. Wood, K. H. Hinkle +2
We present near infrared velocity curves for 12 long period variables (LPVs) in the globular cluster 47 Tuc (NGC 104). New light curves are also presented for these variables. Resu…
A study of bright Southern Long Period Variables
T. Lebzelter, K. H. Hinkle, P. R. Wood +2
In this paper we present radial velocity curves of AGB variables that exhibit various kinds of anomalies: Semiregular variables (SRVs) with typical mira periods, SRVs exceeding the…
4mu spectra of AGB stars I: Observations
T. Lebzelter, K. H. Hinkle, B. Aringer
We present times series of high resolution spectra of AGB variables at 4mu. Line profiles from the major contributors to the spectra of oxygen rich stars at 4mu, OH, HO, HCl an…
Mira's wind explored in scattering infrared CO lines
N. Ryde, B. Gustafsson, K. Eriksson +1
We have observed the intermediate regions of the circumstellar envelope of Mira (o Ceti) in photospheric light scattered by three vibration-rotation transitions of the fundamental…
