INTRODUCTION
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.
Elipe, J. F. Ling, C. Prieto and V. Tamazian. Thanks to the LOC, many ofthe participants
discovered that Galicia is a nice green country and privileged gastronomical site. Local
sponsors were, besides the University itself, the Xunta de Galicia and the Ministerio de
Educacion. To all of them, LOC and sponsors, our thanks.
The Proceedings include lectures and communications presented at the meeting. We are
indebted to the referees who carefully reviewed the papers, resulting in many improvements
in the form and content of the papers.

OPENING SESSION
Word of welcome by the Rector of the University of Santiago de Compostela, Professor
Villanueva
On behalf of the University of Santiago de Compostela I would like to express our
gratitude for your participation in the International Workshop Visual Double Stars: For
mation, Dynamics and Evolutionary Tracks organized by the University of Santiago de
Compostela.
The century-old tradition and Santiago's contribution to the formation of Europe have
lately brought the city international recognition. Thus, Santiago has been declared Her
itage of Humanity and the road to Santiago has been acknowledged as the most important
cultural European route.
The Royal University of Santiago de Compostela, founded five centuries ago on the
initiative of Lope Gomez de Marzoa, has taken profit of the dynamic use of the cultural
and scientific heritage arisen from the Way to Santiago leading us to explore new motives
and itineraries leading to the same final destination.
In this regard, we have developed a new network, called the Compostela Group of
Universities integrated by 70 Universities from 17 different European countries. This ini
tiative has as its main aim the development of cooperation agreements in the academic,
cultural and scientific fields this understood as a social phenomenon that has contributed
decisively to encounter the concept and the personality of Europe.
I would also deal with the coordination of the different activities in the field of the
university international relations, the development of specific mechanisms for the imme
diate transmission of information, and the exchange and promotion of contacts among
member universities and other interested universities, promoting social, educational and
technological development with neighbouring countries, communities and regions.
Our five hundred years anniversary is the time to take stock of the tremendous scientific
revolution that have occurred over the last decades and to discuss its impact on our future
higher education schemes. This University has developed a great research capacity and
potential in various fields, including Astronomy, first of all because the efforts of Prof.
Ramon Maria Aller.
It is a great honour and privilege for me to welcome you to the University of Santiago
de Compostela. I admire you for your high quality science and organizational capacity and
last, but not least, for your warm and loveable personality.
