On the metallicity of open clusters. III. Homogenised sample
Open clusters are known as excellent tools for various topics in Galactic research. For example, they allow accurately tracing the chemical structure of the Galactic disc. However, the metallicity isExpand
The Gaia-ESO Public Spectroscopic Survey
The Gaia-ESO Public Spectroscopic Survey has begun and will obtain high quality spectroscopy of some 100000 Milky Way stars, in the field and in open clusters, down to magnitude 19, systematically ...
On the metallicity of open clusters - II. Spectroscopy
Context. Open clusters are an important tool for studying the chemical evolution of the Galactic disk. Metallicity estimates are available for about ten percent of the currently known open clusters.Expand
Chemically peculiar stars and their temperature calibration
Aims. The determination of effective temperature for chemically peculiar (CP) stars by means of photometry is a sophisticated task due to their abnormal colours. Standard calibrations for normalExpand
On the metallicity of open clusters - I. Photometry
Context. Metallicity is one of four free parameters typically considered when fitting isochrones to the cluster sequence. Unfortunately, this parameter is often ignored or assumed to be solar in mostExpand
A new catalogue of Stroemgren-Crawford uvbybeta photometry
A new all-sky catalogue of all available uvbybeta measurements from the literature was generated. The uvbybeta photometric system is widely used for the study of various Galactic and extragalacticExpand
Peranso - Light curve and period analysis software
An introduction to Peranso and its functionality is given, which offers a complete set of powerful light curve and period analysis functions to work with large astronomical data sets. Expand
On the current status of open-cluster parameters
We aim to characterize the current status of knowledge on the accuracy of open-cluster parameters such as the age, reddening and distance. These astrophysical quantities are often used to study theExpand
New magnetic chemically peculiar stars
Our observations with the 6-m telescope revealed six new magnetic chemically peculiar (CP) stars among objects with large depressions in the continuum: HDE 293764, BD+17°3622, HD 169887, HDE 231054,Expand
New variable chemically peculiar stars identified in the Hipparcos archive
Since variability of chemically peculiar (CP) stars plays an important role for the astrophysical explanation of their outstanding behaviour, we have identified new variable CP stars listed inExpand
