Intense Mass Loss from C-rich AGB Stars at low Metallicity?
L. Mattsson, R. Wahlin, S. Höfner +1
We argue that the energy injection of pulsations may be of greater importance to the mass-loss rate of AGB stars than metallicity, and that the mass-loss trend with metallicity is…
The Chemical Composition of Red Giants, AGB Stars and Planetary Nebulae
Bengt Gustafsson, Rurik Wahlin
The determinations of element abundances in red-giant stars and in particular in AGB stars are reviewed and the resulting abundances are compared with those obtained for planetary…
Carbon stars in local group dwarf galaxies: C and O abundances
R. Wahlin, K. Eriksson, B. Gustafsson +4
We present abundances of carbon and oxygen as well as abundance ratios 12C/13C for a sample of carbon stars in the LMC, SMC, Carina, Sculptor and Fornax dwarf galaxies. The overall…
X-RED: A Satellite Mission Concept To Detect Early Universe Gamma Ray Bursts
Mirko Krumpe, Deirdre Coffey, Georg Egger +14
Gamma ray bursts (GRBs) are the most energetic eruptions known in the Universe. Instruments such as Compton-GRO/BATSE and the GRB monitor on BeppoSAX have detected more than 2700 G…
Chemical analysis of carbon stars in the Local Group: I. The Small Magellanic Cloud and the Sagittarius dwarf spheroidal galaxy
P. De Laverny, C. Abia, I. Dominguez +5
We present the first results of our ongoing chemical study of carbon stars in the Local Group of galaxies. We used spectra obtained with UVES at the 8.2 m Kueyen-VLT telescope and…
The Abundance of Elements in Cool Stars, as Determined from High-Resolution, 1-5 Micron Spectroscopy
N. Ryde, B. Gustafsson, K. Eriksson +1
We review the field of abundance determinations of elements in cool stars, with special interest paid to determinations based on analyses of high-resolution, 1-5 micron spectra. We…
