| Abstract: | We have begun a project to determine the dynamical properties of the galactic open cluster system. For this purpose we need information about the proper motions, distances, radial velocities and ages of the open clusters. As a first step we have searched the Hipparcos Catalogue for open cluster members. Our search resulted in a list of about 730 probable or possible members, which will enable us to determine the proper motions of nearly 220 open clusters. We found evidence for the membership of several cepheids and other stars of astrophysical interest in open clusters. We could also confirm or reject several dubious star clusters. |
