Wide-band X-ray spectrum and 2-10 keV lightcurve of AB Doradus and Algol, a rapidly rotating young star and an eclipsing binary system. Large flare events, followed for their entire duration, were detected in both cases. These observations show for the first time that hard X-ray emission (>20 keV) is produced during stellar flares.
