Abstract
The Algol system was observed on August 18/19,1983 with different combinations of three instruments aboard EXOSAT: the low-energy channel multiplier array, the medium-energy proportional counters, and the transmission grating spectrometer. The X-ray flare observed on August 19 was analyzed and the decay phase was studied. It is shown that during this phase the flare cools quasistatically according to the scaling laws and analytical expressions for the time-evolution of the relevant physical quantities are presented.
