Recent advances in observational and theoretical efforts in
understanding the nature of cataclysmic variables had reached such
maturity that there existed a strong, shared feeling among the
workers in this field that an international colloquium sponsored by
the International Astronomical Union would be timely. To be more
specific, this was due primarily to the accumulation of the new
data from satellite observatories, such as the International
Ultraviolet Observatory (IUE) and EXOSAT, as well as ground-based
optical and radio telescopes, and the advances in modeling the
putative accretion disks and the thermo-nuclear run-away phenomena
in the vinicity of the white dwarf stars in cataclysmic variables.
A series of workshops on this subject held in North America over
the past several years and that held in Europe in 1985 had all
contributed to the advances in our knowledge that led to IAU
Colloguium No. 93, held in Bamberg from the 16th to 19th of June
1986. In all, 157 astronomers from 27 countries participated in
this conference. Judging from the papers presented, both invited
and contributed, and from the enthusiasm seen in discussions, the
meeting was indeed a success.
Comets are always very impressive phenomena. Their appearances at
regular, but mostly irregular, times excite people who see them.
Astronomers have the obvious advantage of being able to see more of
comets, and to study them. Their enthusiasm is reflected in the 50
papers in this book, written by more than 90 experts. The reviews
in this book clearly describe a landmark in the history of cometary
studies. Knowledge gathered up to and including Comet Halley are
presented in two volumes. The first volume is about general aspects
of observing and studying comets, where they originate and how
their evolution develops. The second volume goes into the details
of what a comet is: the nucleus, the coma, cometary dust, plasmas
and magnetic fields. The book ends with a reflection by Fred
Whipple about Comets in the Post-Halley Era. The book discusses all
aspects of comets and is therefore suitable for use in graduate
level courses. All astronomers and geophysicists interested in
comets will find very useful and well-presented information in this
book.
Are there other planetary systems like ours? Other planets like
ours? Is there life elsewhere in the Universe?' So asks Dr. Lew
Allen Jr. in the Foreword. In December of 1992, theorists,
observers, and instrument builders gathered at the California
Institute of Technology to discuss the search for answers to these
questions. The International Conference, entitled Planetary
Systems: Formation, Evolution, and Detection' and supported through
NASA's newly formed TOPS (Toward Other Planetary Systems) program,
was the first of a series of conferences uniting researchers across
disciplines and political boundaries to share thoughts and
information on planetary systems. The conference was sponsored by
NASA, hosted by JPL at Caltech, and endorsed by the 1992
International Space Year Association. These proceedings include
discussions of topics ranging from stellar, disk, and planetary
formation to new ways of searching for other stellar systems
containing planets. The authors represent a wide range of
nationalities, disciplines, and points of view. The second
international conference took place in December of 1993.
The Bosscha Observatory in Lembang, Java, Indonesia, celebrated in
1983 its 60th anniversary. Since its foundation, the physical
properties of binary systems have formed a major research topic of
this observatory. Until 1970, the study of visual binaries and the
determination of orbits received most emphasis. Since then, also
the evolution of close binary systems, such as X-ray binaries,
Wolf-Rayet binaries and binary pulsars, has been researched with
priority in Lembang. It seemed thus appropriate that a Colloquium
devoted to the study of binary systems be held in Lembang at the
time of the Observatory's anniversary. In the Colloquium, the role
of wide double (and multiple) systems received special emphasis -
not only because of the long tradition of visual binary research at
Lembang; but also because their role in documenting stellar
evolution has been largely overlooked in recent decades, and needs
to be brought into focus with the information forthcoming from
close binaries. The Colloquium covered the physical properties of
visual as well as close binary systems, and their generic
relations, in the broadest possible sense. It was sponsored by the
International Astronomical Union as IAU Colloquium No. 80 ('Double
Stars, Physical Properties and Generic Relations'). After the
official opening ceremony, the meeting started with a discussion on
the future of astronomy in Asia. The scientific sessions began with
the 'V. Bappu Memorial Lecture on the Evolution of Binary Systems',
presented by Z. Kopal.

Your Magnificences, my Lord Mayor, ladies and gentlemen! It is a
great pleasure for me to respond, on behalf of your foreign guests,
to your gracious words of welcome; and to thank you for the
wonderful reception which you nave extended to us. The city of
Bamberg and its Remeis Sternwarte nas indeed been renowned allover
the world for a great many years - as the place where your
Observatory's first director, Professor Ernst Hartwig (1851-1923) -
in addition to his other titles to fame - collaborated (with Gustav
Muller of Potsdam) on the construc- tion of the monumental
Geschichte und Literatur des Lirhtwechsels der Veranderlichen
Sterne, which since 1918 has (together with its sub- sequent
continuation) been a veritable vade-mecum of a1l students of
variable stars; where the second director, Professor Ernst Zinner
(1886-19]~ prepared his valuable Katalog der Verdachtigen
Veranderlichen Sterne (192@ which safeguarded many an astronomer
(including the present speaker in the days of his innocence) from
premature discovery claims; and whose third director, Professor
Wolfgang Strohmeier, initiated in 1959 the tradition of the
international colloquia of which ours is the latest successor. It
is indeed a great pleasure to welcome Professor Strohmeier - now
Emeritus - among us; and to congratulate him on the grace with
which he is carrying his years.
During the past years, a number of international astronomical
conferences were held at the Remeis-Observatory in Bamberg, four of
them sponsored by the International Astronomical Union. The first
meeting was organized in 1959 and dealt with Variable Stars, the
last one was held in 1981 and focussed on 'Binary and Multiple
Stars as Tracers of Stellar Evolution'. The present conference was
organized to commemorate the 200th anniversary of the birth of
Friedrich Wilhelm Bessel, who was born in Minden on July 22, 1784,
and died in Konigsberg on March 17, 1846. When the plan for an
international conference on astrometric binaries was presented to
several colleagues, we received enthusiastic support and decided to
pursue the idea. A Scientific Organizing Committee was soon
established, consisting of: Z. Kopal Manchester, u.K. S. M. Gong
Nanjing, China (Chairman) M. Grewing Tiibingen, F.R.G. V. Abalakin
Pulkovo, U.S.S.R. P. v. d. Kamp Amsterdam, Netherlands J. Dommanget
Uccle, Belgium M. Kitamura Tokyo, Japan M. G. Fracastoro Torino,
Italy J. Rahe Bamberg, F.R.G. W. Fricke Heidelberg, F.R.G. Ya.
Yatskiv Kiev, U.S.S.R. E. H. Geyer Bonn, F.R.G. The meeting took
place in Bamberg at the Remeis-Observatory, Astronomical Institute
of the University Erlangen-Nurnberg, from June l3 to 15, 1984. The
following institutions generously supported the meeting: Deutsche
Forschungs- gemeinschaft, Bonn; Stadt Bamberg; Universitat Bamberg;
Universitat Erlangen- Nurnberg; University of Manchester.
The systematic study of the planets has experienced a slow but
steady progress from the efforts of a single individual (Galileo
Galilei, 1564-1642) to nations that individually and collectively
create whole agencies and complex infrastructures devoted to the
exploration and understanding of our solar system. This quest for
knowledge continues in earnest today as we attempt to understand
Earth's unique place among its closest neighbors. Known diversities
emphasize fractionation processes that may have occurred in the
nebula during early solar system formation, and the vastly
different evolutionary paths taken by the planets and their
satellites. The discovery of similarities and differences among the
planets has given rise to a discipline of "Comparative Planetology.
" Here terrestrial properties and giant planet atmospheres are
viewed and probed, surface geologies are related to atmospheres and
oceans, interior structures are envisioned, magnetic fields mapped,
and bizarre differences in satellites and ring systems continue to
enlighten, amaze and confound the detectives of planetary science.
A science organizing committee with international participation was
formed to develop a conference program to address the basic issues
and the fundamental processes that are common among the planets.
The goals of the meeting were twofold: first the production of a
reference source on comparative planetology for academia, and
second, the provision of an impetus for NASA to begin a program
devoted to this emerging science discipline. The conference program
accommodated seventeen invited papers and nineteen poster
presentations.
The idea of having a conference in Padova describing the results
obtained by the Galileo spacecraft and the characteristics of the
Telescopio Nazionale Galileo began in 1995, when a number of
colleagues from both sides of the Atlantic began exchanging
suggestions and ideas. Looking at the schedules of the two teams,
it was clear that the beginning of January 1997 would be a good
time to hold the conference; these dates also luckily coincided
with the dates of the memorable discovery of the Medicean moons of
Jupiter by Galileo Galilei in Padova in 1610. To emphasize these
three elements, the name of the conference was then proposed and
accepted by the involved parties: NASA and JPL in the United
States, the German space agency DARA, the University of Padova, and
the Astronomical Observatory in Padova. I wish to recall a few key
dates: In January 1610, Galileo--from his house in Padova--had the
first hint of three and then four stars connected to Jupiter. In
December 1995, the probe released from the spacecraft entered the
atmosphere of Jupiter, and the spacecraft entered orbit about
Jupiter. These extraordinary events were followed at JPL by a
number of representatives of many institutions and space agencies.
In June 1996, the Telescopio Nazionale Galileo was inaugurated by
the King of Spain Juan Carlos I, in the presence of Prof. Luigi
Berlinguer, Minister of University and Science. These ceremonies
occurred as the spacecraft started touring the moon Europa.
