We present a re-analysis of the Geneva-Copenhagen survey, which benefits from the
infrared flux method to improve the accuracy of the derived stellar effective temperatures and …

Aims. Synthetic spectra are needed to determine fundamental stellar and wind parameters
of all types of stars. They are also used for the construction of theoretical spectral libraries …

Context. Open clusters are ideal test particles for studying the chemical evolution of the
Galactic disc. However, the number and accuracy of existing high-resolution abundance …

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 …

Context. Gas expulsion is a central concept in some of the models for multiple populations
and the light-element anti-correlations in globular clusters. If the star formation efficiency was …

The Kepler space mission provided near-continuous and high-precision photometry of about
207 000 stars, which can be used for asteroseismology. However, for successful seismic …

We find that the initial dust masses in planetary debris disks are correlated with the
metallicities of their central stars. We compiled a large sample of systems, including Spitzer …

In this paper, we present a new catalogue of chemically peculiar (CP) stars obtained by
compiling publications in which abundances of metals are provided. Our catalogue includes …

We describe a new survey for unbound hypervelocity stars (HVSs), stars traveling with such
extreme velocities that dynamical ejection from a massive black hole is their most likely …

This paper presents the results of magnetic field measurements for 39 chemically peculiar
and 3 normal main sequence stars used as standard stars. Observations were carried out …
