PREFACE
Accretion Disks represent the characteristic flow pattern through which compact
astrophysical objects accrete gas and liberate its gravitational energy. They are
thus a fundamental element in all high energy sources powered by accretion. Their
importance ranges from close stellar binaries over disks around young and still form
ing stars to quasars and the cores of active galaxies where very massive black holes
accrete mass from a surrounding gaseous disk.
In 1989 a first NATO Advanced Research Workshop "Theory of Accretion Disks"
was held in Garching. It brought together leading experts from different research
areas to intensely discuss achievements and future propects under the common the
oretical paradigm: The Accretion Disk.
Now, four years later, the fundamental role of accretion disks in astrophysics has
become even more visible. Significant progress in detector technologies all over the
electromagnetic spectrum and modern methods of evaluation have accumulated an
impressive body of knowledge in all areas. This is paralleled by intensive theoretical
work that has brought to light and clarified essential physical processes in these
accretion disks. It therefore seemed appropriate to again call together an expert
meeting, the second NATO Advanced Research Workshop "Theory of Accretion
Disks - 2" , which took place at the Max-Planck-Institut flir Astrophysik, Garching,
from March 22 to 26, 1993. It brought together a significant fraction of the most ac
tive researchers in the field and led to an intense and fruitful interaction between the
participants coming from different areas of expertise. The present volume contains
the reviews and presentations of this conference and, we hope, gives a fair· cross
section of our present knowledge and understanding of Accretion Disks. We also
wish that, as did the first Workshop, it will fruitfully contribute to future research
efforts.
We are greatly thankful to the NATO Science Committee for providing the main
funding for this Workshop, and to the Max-Planck-Society for providing substantial
additional support. We thank the director, Prof. W. Hillebrandt, and the members
of Max-Planck-Institut flir Astrophysik for their hospiltality and the welcoming envi-

ronment during the Workshop, and extend our gratitude to the Institute in Garching
and to the Institut fur Theoretische Astrophysik, Heidelberg, for use of facilities and
support before, during and after the meeting. Precision Software GmbH, SUN Mi
crosystems, and Tektronix GmbH have helped us to put together thew registration
folder. We thank all the participants for their lively contributions to the discussions
and for the prompt submissions of their manuscripts. Finally we would like to thank
Kate O'Shea and Petra Berkemeyer for organizatorial and secretarial help.
