These meetings consisted of the presentation of scientific results by junior as well as senior members of the group, and by discussions betwen the participants. As such, the SUA meetings became a forum for the exchange of ideas, and for asking questions and advice in an informal atmosphere. At the occasion of Prof. Cees de Jager's 80th birthday, we decided to collect the presented talks in written form as a Festschrift in honour of this well-respected and much beloved scientist, teacher and friend.

The first three papers deal with the personality of Cees de Jager, more specifically with his role as a supervisor to young researchers and as a catalyst in the research work of his colleagues. And about his remarkable role in the establishment of astronomy education and research at the University of Brussels. The nest presentation deals with solar research, a field in which Cees was prominently active for many years. Then follow several papers dealing with stars about which Cees is a true expert: massive stars.
