Short Time

Four years ago, in 1975, we met in Cambridge, England for our first IAU Symposium devoted entirely to binary stars. Most of the talks given there were theoretical, and at the end some of us felt that it would be appropriate to organize yet another Symposium soon, this time oriented more towards observations and their immediate interpretation. This is why we have come together here in Toronto. Four years is not a long interval of time, and few disciplines of astronomy repeat their Symposia on such a short time scale. While the need for another Symposium was clear to the binary stars investigators, it is not so obvious to other colleagues. We must therefore be very grateful to the Executive Committee of the International Astronomical Union for their great understanding of our needs. This understanding went far beyond approving and sponsoring this meeting: We have received a substantial financial assistance, which all went to the support of the travel expenses of some of the participants. Many more travel grants were possible thanks to a most generous support by the University of Toronto. I would like to thank both institutions.

AbstractBenjamin Baillaud was appointed president of the First Executive Committee of the International Astronomical Union which met in Brussels during the Constitutive Assembly of the International Research Council (IRC) on July 28th, 1919. He served in this position until 1922, at the time of the First General Assembly of the IAU which took place in Rome, May 2–10. At that time, Baillaud was director of the Paris Observatory. He had previously been director of the Toulouse Observatory for a period of 30 years and Dean of the School of Sciences of the University of Toulouse. He specialized in celestial mechanics and he was a strong supporter of the “Carte du Ciel” project; he was elected chairman of the permanent international committee of the Carte du Ciel in 1909. He also was the founding president of the Bureau International de l’Heure (BIH) and he was directly involved in the coordination of the ephemerides at an international level. In this paper, we present some of his activities, particularly those concerning international programmes, for which he received international recognition and which eventually led to his election in 1919 to the position of first president of the IAU. We also briefly recount the very first meetings and years of the IAU.

AbstractThe USA delegation to the July 1919 International Research Council meeting in Brussels included Joel Stebbins, then professor of astronomy and observatory director at the University of Illinois, as secretary of the executive committee appointed by the National Research Council. Stebbins, an avid photographer, documented the travels of their party as the American astronomers attended the meeting and later toured devastated towns, scarred countryside, and battlefields only recently abandoned. Published reports of the meeting afterward attest to the impression left on the American visitors, and the photographs by Stebbins give us a glimpse through their own eyes. Selected photographs, recently discovered in the University of Wisconsin Archives and never before publicly seen, will be presented along with some commentary on their significance for the International Astronomical Union, which took shape at that 1919 meeting.

The initiative in the organization of the conference was taken by the President of Commission 33 of the International Astronomical Union and financial aid was received from U.N.E.S.C.O. At the invitation of Dr P. J. van Rhijn, Director of the Kapteyn Astronomical Laboratory, Groningen, the meeting was held in the estate ‘Vosbergen’ near the city of Groningen and owned by the University of Groningen. The organizing committee consisted of J. H. Oort (Chairman), W. Baade, B. J. Bok, Ch. Fehrenbach, B. Lindblad, W. W. Morgan, P. P. Parenago, and A. Blaauw (Secretary), all of whom attended the conference. The other participants, who were invited either because they represented institutions which might take part in future galactic research, or because of the character of their research, were V. A. Ambartsumian, W. Becker, P. Couderc (representing the Commission for the Carte du Ciel), G. Haro, O. Heckmann, H. Spencer Jones, B. V. Kukarkin, J. J. Nassau, P. Th. Oosterhoff, L. Plaut (local Secretary), J. M. Ramberg, C. Schalen, J. Schilt, R. H. Stoy, B. Strömgren, P. J. van Rhijn. V. Kourganoff, P. G. Kulikovsky and O. A. Melnikov were present as interpreters.

At the end of this year, the Sonderforschungsbereich (Special Collaborative Programme) no. 132 on “Theoretical and Observational Stellar Astronomy” in Heidelberg will terminate after fifteen years. Although 15 years are only 2 1/2 per cent of the age of the University of Heidelberg, which is celebrating its 600 th anniversary this year, they are nevertheless a long and important time for astronomical research in Heidelberg. On the occasion of the termination of the Sonderforschungsbereich, we are now given the opportunity to present an essential part of its research, namely that on circumstellar matter at an international conference, and we are grateful to the International Astronomical Union that this could be realized, and that we can welcome here so many participants to this Symposium. As the Speaker of our Sonderforschungsbereich I would like to briefly introduce to you the general concept of the institution of an SFB and give an overview over its structure and research activities.

My last attendance at a meeting of the International Astronomical Union was forty-four years ago when it met in Paris in 1935. I do not doubt that my being asked to give an invited discourse at this meeting is a personal courtesy extended to me by your distinguished President recalling, perhaps, the years when he and I were colleagues together at the University of Chicago.I am aware that associated with my absence from these meetings for nearly half a century is the fact that during most of this period - if not all of it - my interests, at different times, have been outside whatever may have been the prevailing trends in the mainstream of astronomy. I am afraid that on this account, the point of view I shall present - retrospectively and prospectively - will not be in conformity with the trends currently prevailing. I must therefore begin by asking for your patience and for your forbearance.Dr. Blaauw, when he invited me to give one of the three discourses at this meeting, suggested that in selecting a topic I might wish to take into account the fact that this year is the centennial of Einstein’s birth. The subject of my discourse is in accordance with that suggestion.

The number of artificial satellites dedicated to astrophysical research is increasing rapidly. Nearly 30 satellites currently under development or in the early planning stages will be in orbit within 10–12 years and will have more sensitive detectors and better data-processing technology as a result of current research. Many of the galactic and extragalactic objects discovered by the new technology are variable on surprisingly short time scales ranging from sub-seconds to many months. The new variable objects include but are not confined to: neutron and binary stars; quasars (and associated active centers of galaxies); newborn infrared stars and associated clouds; the coronal activity of main sequence stars; cataclysmic variables (white dwarfs in binaries); and novae, supernovae and remnants. We now realize that the short time-scale variations of many unusual stars and active galactic nuclei demand that ground and space data be taken as close in time as possible and that they be carefully planned and coordinated.

A conference having the title The Three Galileos: the Man, the Spacecraft, the Telescope, was held at the University of Padova from 7-10 January 1997. The conference was jointly organized by the U.S. space agency NASA, JPL, the German space agency DARA, the University and Astronomical Observatory of Padova, and the Telescopio Nazionale Galileo, with the added support of the International Astronomical Union. The scientific committee was composed of: C. Barbieri (Chairman, University of Padova), S. Atreya (University of Michigan), E. Bellone (University of Padova), M. Belton (NOAO), P. Benvenuti (ESA), F. Bertola (University of Padova), M. Calvani (Astronomical Observatory of Padova), G. Cariolaro (University of Padova), W. Ip (Max-Planck-Institute for Aeronomy), T. Johnson (JPL), T. Owen (University of Hawaii), J. Rahe (NASA), and R. West (ESO). The purpose was to discuss the discovery of the Medicean Moons by Galileo Galilei in Padova from 7-15 January 1610, the results of the Galileo spacecraft during the cruise phase and while orbiting the Jovian system, and the construction of the 3.5-m active-optics Italian telescope Galileo (TNG) in the Canary Islands.

The four years that have elapsed since the last meeting of the International Astronomical Union have witnessed steady progress in the determination of radial velocities, principally at the Mt Wilson Observatory, Pasadena, Cal., the Lick Observatory, Mt Hamilton, Cal., the Yerkes Observatory, Williams Bay, Wis., the Dominion Astrophysical Observatory, Victoria, B.C., the Observatory of the University of Michigan, Ann Arbor, Mich., and the Simeis Observatory in Russia. It will be useful, for the members of the Commission, to give a short summary of the radial velocity work completed and in progress since the last meeting.
