EXOSAT light curve of Algol
An observation of the stellar system Algol showing a 3 hour X-ray flare which had at its peak a luminosity of 1031 ergs/sec and a temperature of 60 million degrees. Detailed analysis of the evolution of the flare shows that this event occurred in a magnetic loop structure with a scale height of 0.2 stellar radii anchored to the K subgiant in the system. The insert shows the X-ray spectrum during the flare.
