Extensive spectroscopic studies of stars with and without planets have concluded that stars hosting planets are significantly more metal-rich than those without...

We present Na, Mg and Al abundances in a set of 98 stars with known giant planets, and in a comparison sample of 41 "single" stars. The results show that the [X...

Listed are the [Mg/Fe], [Ca/Fe], [Ti/Fe] and [Si/Fe] abundance ratios for 650 K giants in four fields of the Galactic Bulge. Abundances were measured using...

We discuss abundances of alpha -elements in the ultra-metal-poor giants CS29498-043 and CS22949-037. The abundance of oxygen has been derived from measurements...

The abundance measurements are based on high-resolution optical spectroscopical data, obtained during 2 observing runs with the Ultraviolet and Visual Echelle...

Numerous spectroscopic studies have shown that stars with giant planets are particularly metal-rich when compared with field stars in the solar neighbourhood. I...

Atomic data and equivalent widths for 15 red clump giants in 5 open clusters: Cr 110, NGC 2099, NGC 2420, M 67, NGC 7789. (2 data files).
