Radial Velocities of Bright Population II F Stars
This catalog presents new radial velocity determinations, based on 2nm/mm Coude plates, for 146 southern stars brighter than m(v)=8.3. Drawn from the catalog of uvby-{beta}... -
Radial velocities of red giants in {omega} Cen
We present the results of a survey of radial velocities over a wide region extending from r~=10 out to 80' (~1.5 tidal radii) within the massive star cluster omega Centauri... -
Deep FORS1 BR photometry of omega Cen
We present the results of a deep photometric survey performed with the VLT FORS1 aimed at investigating the complex main-sequence structure of the stellar system Centauri. We... -
gri photometry of variables in NGC 4258
We present results of a ground-based survey for Cepheid variables in NGC4258. This galaxy plays a key role in the Extragalactic Distance Scale due to its very precise and... -
Space velocities orbits in the Milky Way halo
We have compiled a sample of 699 stars from the recent literature with detailed chemical abundance information (spanning -4.2<~[Fe/H]<~+0.3), and we compute their space... -
VI light curves of Galactic Bulge Cepheids
The fourteenth part of the OGLE-III Catalog of Variable Stars (OIII-CVS) contains Cepheid variables detected in the OGLE-II and OGLE-III fields toward the Galactic bulge. The... -
G64-12 and G64-37 linelist and EWs
Studies of extremely metal-poor stars indicate that chemical abundance ratios [X/Fe] have a root mean square scatter as low as 0.05dex (12%). It remains unclear whether this... -
Abundance analysis of HD 140283
HD 140283 is a reference subgiant that is metal poor and confirmed to be a very old star. The abundances of this type of old star can constrain the nature and nucleosynthesis...
