Kinematics of Nearby Subdwarf Stars
M. I. Arifyanto, B. Fuchs, H. Jahreiss +1
We present an analysis of the space motions of 742 subdwarf stars based on the sample of Carney et al. (1994, CLLA). Hipparcos parallaxes, TYC2+HIP proper motions and Tycho2 proper…
The evolution of the Milky Way monitored in the solar neighbourhood
B. Fuchs, C. Dettbarn, H. Jahreiss +1
In this review we concentrate on the dynamical evolution of the Milky Way as monitored in the solar neighbourhood. The relevant data sets are presented and discussed in detail. In…
Absolute Proper Motions of Open Clusters: I. Observational data
H. Baumgardt, C. Dettbarn, R. Wielen
Mean proper motions and parallaxes of 205 open clusters were determined from their member stars found in the Hipparcos Catalogue. 360 clusters were searched for possible members, e…
The combination of ground-based astrometric compilation catalogues with the HIPPARCOS Catalogue. II. Long-term predictions and short-term predictions
R. Wielen, H. Lenhardt, H. Schwan +1
The combination of ground-based astrometric compilation catalogues, such as the FK5 or the GC, with the results of the ESA Astrometric Satellite HIPPARCOS produces for many thousan…
A Finding List for Delta_mu Binaries derived from a Comparison of HIPPARCOS Proper Motions with Long-term Averaged Data
Roland Wielen, Christian Dettbarn, Hartmut Jahreiss +3
The comparison of quasi-instantaneously measured HIPPARCOS proper motions with long-term averaged proper motions, derived from ground-based data, allows the identification of many…
Polaris: astrometric orbit, position, and proper motion
R. Wielen, H. Jahreiss, C. Dettbarn +2
We derive the astrometric orbit of the photo-center of the close pair alpha UMi AP (=alpha UMi Aa) of the Polaris multiple stellar system. The orbit is based on the spectroscopic o…
