These results include the determination of the temperature structure of stellar coronae, the detection for the first time of hard (>20 keV) X-ray emission tails, the determination of coronal abundances and the time evolution of coronal parameters (including metallicity) in the course of flares. We show several examples of the acquired data with emphasis on observations by our team of the RS CVn binaries UX Ari, HR 1099 and II Peg, of the flare star YY Gem and of the young ZAMS star AB Dor. We present the observational results and the modeling carried out for their interpretation.CD-ROM o DVDenConference posterFIS/05 - ASTRONOMIA E ASTROFISICA
