The radiative-convective gap: fact or fiction?
Wolfgang Brandner, Artur Sorg, Siegfried Röser +1
Gaia characterizes the stellar populations of nearby open clusters with unprecedented precision. We investigate the Böhm-Vitense gap, which has been found as a prominent feature in…
Reanalysis of nearby open clusters using Gaia DR1/TGAS and HSOY
Steffi X. Yen, Sabine Reffert, Elena Schilbach +3
Open clusters have long been used to gain insights into the structure, composition, and evolution of the Galaxy. With the large amount of stellar data available for many clusters i…
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…
On the origin of field O-type stars
E. Schilbach, S. Roeser
Aims: We try to identify the origins of field O-stars in the nearest 2 to 3 kpc around the Sun using the best presently available kinematic data on O-stars and on young open cluste…
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…
