The detached dust and gas shells around the carbon star U Ant
M. Maercker, H. Olofsson, K. Eriksson +2
Context: Geometrically thin, detached shells of gas have been found around a handful of carbon stars. --Aims: Previous observations of scattered stellar light in the circumstellar…
Evidence of enrichment by individual supernova from elemental abundance ratios in the very metal-poor dSph galaxy Bootes I
S. Feltzing, K. Eriksson, J. Kleyna +1
Aim: We establish the mean metallicity from high-resolution spectroscopy for the recently found dwarf spheroidal galaxy Bootes I and test whether it is a common feature for ultra-f…
CNO abundances of HdC and RCB stars: a view of the nucleosynthesis in a white dwarf merger
D. A. Garcia-Hernandez, K. H. Hinkle, David. L. Lambert +1
We present high-resolution (R~50,000) observations of near-IR transitions of CO and CN of the five known hydrogen-deficient carbon (HdC) stars and four R Coronae Borealis (RCB) sta…
