Visual Double Stars: Formation, Dynamics and Evolutionary Tracks / Edition 1

by J.A. Docobo, A. Elipe, H. McAlister

Overview

This workshop is devoted to Double stars. The general topics of the meeting were: for­ mation, dynamics and evolutionary tracks. In accordance with the pure tradition of the Saint James way, "pilgrims" from all over the world come to meet together in Santiago. Although with a common interest (double stars), this meeting was a multidisciplinary one, since scientists with different backgrounds participated in it. As a matter of fact, we think that this is the first workshop jointly supported by IAU Commissions 7 (Celestial mechanics) and 26 (Double and multiple stars). It is our belief that this meeting will be the origin of a more close relations and common research. This meeting was held under the invitation of the University of Santiago de Compostela to commemorate its fifth centenary, and organized by the Astronomical Observatory named after its founder, Ramon M. Aller, who made significant contributions in the study of visual double stars, and was one of the pioneers who put the seeds of the present blossoming of Astronomy in Spain. The Scientific Organizing Committee was formed by Drs. C. Allen, P. Couteau, J. A. Docobo, R. Dvorak, A. Elipe, S. Ferraz-Mello (co-chairman), H.A.McAlister, M. Valtonen, C.Worley (chairman) and H. Zinnecker. The Local Organizing Committee was formed by Drs. J. A. Docobo (chairman), A.

Editorial Reviews

The proceedings of an international workshop held in Santiago de Compostela, Spain, in July and August 1996. The 59 lectures and contributed papers cover observations and their results, formation and evolution, dynamics, astrometric data from satellites, and catalogues and databases. Among the topics of the lectures are the construction of the Washington Visual Double Star Catalog and its future, the contribution of HIPPARCOS to binary evolutionary research, the numerical treatment of small stellar systems with binaries, searches for planets around neutron stars, the maximum ages of trapezium systems, and 20 years of speckle interferometry. A few of the papers are in French. Some are also published in vol. 67 no. 2 (1997). No index. Annotation c. by Book News, Inc., Portland, Or.
