Shape parameters of Galactic open clusters
N. V. Kharchenko, P. Berczik, M. I. Petrov +4
(abridged) In this paper we derive observed and modelled shape parameters (apparent ellipticity and orientation of the ellipse) of 650 Galactic open clusters identified in the ASCC…
PPM-Extended (PPMX) - a catalogue of positions and proper motions
S. Roeser, E. Schilbach, H. Schwan +3
Aims: We build a catalogue PPM-Extended (PPMX) on the ICRS system which is complete down to a well-defined limiting magnitude and contains the best presently available proper motio…
Revisiting the population of Galactic open clusters
A. E. Piskunov, N. V. Kharchenko, S. Röser +2
We present results of a study of the galactic open cluster population based on the all-sky catalogue ASCC-2.5 (I/280A) compiled from Tycho-2, Hipparcos and other catalogues. The sa…
An analytical description of the disruption of star clusters in tidal fields with an application to Galactic open clusters
Henny Lamers, Mark Gieles, Nate Bastian +3
We present a simple analytical description of the disruption of star clusters in a tidal field, which agrees excellently with detailed N-body simulations. The analytic expression c…
