Synopses & Reviews
This book contains the proceedings of the first large IAU Symposium dedicated to the bulges of spiral galaxies. Detailed attention is paid to the bulge of our Milky Way system, one of the major building blocks of this system. Topics include the definition of the bulge in our Galaxy and its relation to the so-called spheroid. Discussions are presented to the stars contained in this bulge, their astrophysical properties and their motions. Metallicity variations appear to be present. The possible existence of a bar in the bulge and its origin and future are discussed. The same topics are discussed in (necessarily) less detail for the bulges of other galaxies. The book contains invited reviews given by N. Arimoto, F. Bertola, H. Dejonghe, T. de Zeeuw, M. Franx, I.S. Glass, H.J. Habing, I. King, J. Kormendy, G.W. Preston, R.M. Rich, G. Stansinska, D.M. Terndrup, and P. Whitelock; the Conference Summary is written by K.C. Freeman.
Synopsis
In the early summer of '89 a very informal meeting on the bulge of our Galaxy was held in Leiden. During that meeting Michael Rich proposed to hold a more properly organised symposium on "Galactic Bulges" in a few years time. After some discussion a Scientific Organising Committee was founded and after some manoeuvring a chairman was chosen, a local organiser was assigned and two editors were given instructions. A good thing about the location of the meeting was that Ghent is a very beautiful city and had never before hosted an IAU symposium. It could be that this, plus the fact that he is a very keen amateur astronomer led H. M. the King of Belgium to offer his patronage to the meeting - an offer that we gratefully and - we hope - gracefully accepted. The meeting took place at a resort some 15 km outside Ghent. Most participants were housed on the premises - a very convenient situation. This feeling of togeth- erness made up for the small shortcomings of the lecture room, which is normally used as a sports hall. The weather was fair, except on the day of the barbecue when pouring rain forced us to go inside.
