No Planet Around HD 219542 B
S. Desidera, R. G. Gratton, M. Endl +8
The star HD 219542 B has been reported by us (Desidera et al. 2003) to show low-amplitude radial velocity variations that could be due to the presence of a Saturn-mass planetary co…
Abundance differences between components of wide binaries
S. Desidera, R. Gratton, S. Scuderi +9
In this paper we present iron abundance analysis for 23 wide binaries with main sequence components in the temperture range 4900-6300 K, taken from the sample of the pairs currentl…
Discovery of a bipolar and highly variable mass outflow from the symbiotic binary StHa 190
U. Munari, T. Tomov, B. F. Yudin +15
A highly and rapidly variable bipolar mass outflow from StHa 190 has been discovered, the first time in a yellow symbiotic star. Permitted emission lines are flanked by symmetrical…
Metal Abundances of Red Clump Stars in Open Clusters: I. NGC 6819
A. Bragaglia, E. Carretta, R. G. Gratton +10
We present an analysis of high dispersion spectra (R~40000) of three red clump stars in the old open cluster NGC 6819. The spectra were obtained with SARG, the high dispersion spec…
