Algol is a triple system containing a 70 hr eclipsing binary (K IV and B8 V) in a 694 day orbit with an A V star. The X-ray emission from this system (Schnopper et al 1976) is thought to be associated with a corona surrounding the lobe filling and synchron ously rotating K IV star. This is based on the similarity of the X-ray spectrum and luminosity of this system to that of the RS CVn binaries which also contain K sub-giants with similar rotation periods and the fact that the luminosity of any coronae surrounding the B8 V and AV companion stars should not be enhanced by rapid rotation (Pallavicini et al 1980, White et al 1980). The Einstein SSS measurement showed the X-ray spectrum to be two component with 6 7 temperatures of 7. 10 K and 3. 10 K (White et al. 1980). As dis cussed by Swank et al. (1981), the problem in understanding stellar coronae in general is how to scale up the solar model to account for the enhanced luminosities. The close to 900 inclination and similar sizes for the Band K stars of 3. 6 and 3. 8 R0 respectively make Algol an ideal candidate for an X-ray eclipse measurement wherein the size of the X-ray emitting coronal structures can be directly measured. In this paper we report a continuous observation through the secondary eclipse of Algol using the EXOSAT Observatory. 2.

The 15th ESLAB symposium was held at the end of June 1981 in Amsterdam with the topic being X-ray astronomy. The aim of this symposium was to bring together the international astrophysical community in order to 1. review the present state of X-ray astronomy in the light of new observations gathered in recent missions and to review data on interesting objects in correlated wavelen8th regions; 2. discuss theoretical models describing the phenomena observed; 3. present ESA's European X-ray Observatory Satellite (EXOSAT) and to discuss future X-ray missions and their associated instrumenta tion. These topics seemed to be so interesting for the scientific community that more than 120 contributions were submitted. Of these, 94 were finally accepted and approximately 200 participants attended the 5-day meeting. The symposium was organised in nine sessions covering the whole field. Every main topic was introduced by a review lecture covering the state of-the-art. The aim of the meeting was to assess the impact of the new X-ray findings on the general astronomical knowled8e. The discussion ranged from non-degenerated stellar X-ray sources and stellar coronae tL supernovae, bursters, globular clusters, normal galaxies and finally to cosmology. In each field the philosophy was to bring together the relevant information obtained in radio, optical and X-ray observations followed by theoretical discussions. A large number of contributed papers were also presented within this framework.
