Title: | X-ray observations of stellar coronae and flares with BeppoSAX | Authors: | Pallavicini, R. FRANCIOSINI, Elena MAGGIO, Antonio COVINO, Stefano TAGLIAFERRI, Gianpiero |
Issue Date: | 2001 | Volume: | X-ray Astronomy 2000 | Editors: | Giacconi, R.; Serio, S.; Stella, L. | Series: | ASTRONOMICAL SOCIETY OF THE PACIFIC CONFERENCE SERIES | Number: | 234 | Abstract: | In the four years since its launch the Italian/Dutch satellite BeppoSAX has obtained many new interesting results on X-ray emission from stellar coronae and transient events. 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. | Note: | Disponibile sul CD-ROM allegato al volume, directory X-ray_CD/Posters/, file rpallavicini.ps | Conference Name: | X-ray Astronomy 2000 | Conference Place: | Mondello (PA) | Conference Date: | 4-9 settembre 2000 | URI: | http://hdl.handle.net/20.500.12386/34851 | ISSN: | 1050-3390 | ISBN: | 1-58381-071-4 | Fulltext: | open |
