The initial luminosity and mass functions of the Galactic open clusters
A. E. Piskunov, N. V. Kharchenko, E. Schilbach +3
(... abridged) The observed luminosity function can be constructed in a range of absolute integrated magnitudes mag, i.e. about 5 magnitudes deeper than in t…
Towards absolute scales of radii and masses of open clusters
A. E. Piskunov, E. Schilbach, N. V. Kharchenko +2
Aims: In this paper we derive tidal radii and masses of open clusters in the nearest kiloparsecs around the Sun. Methods: For each cluster, the mass is estimated from tidal radii d…
Population analysis of open clusters: radii and mass segregation
E. Schilbach, N. V. Kharchenko, A. E. Piskunov +2
Aims: Based on our well-determined sample of open clusters in the all-sky catalogue ASCC-2.5 we derive new linear sizes of some 600 clusters, and investigate the effect of mass seg…
109 new Galactic open clusters
N. V. Kharchenko, A. E. Piskunov, S. Röser +2
We present a list of 130 Galactic Open Clusters, found in the All-Sky Compiled Catalogue of 2.5 Million Stars (ASCC-2.5). For these clusters we determined and publish a homogeneous…
Astrophysical parameters of Galactic open clusters
N. V. Kharchenko, A. E. Piskunov, S. Röser +2
We present a catalogue of astrophysical data of 520 Galactic open clusters. These are the clusters, for which at least three most probable members (18 on average) could be identifi…
