| Abstract: |
We present the results of a Beppo-AX} observation of the short-period eclipsing binary star HD 9770. The Beppo-SAX data confirm that this is a very active coronal source, with strong flare activity. The 0.1-10 keV light curve is modulated by the star rotation with the eclipse detected at all energies. However, there seem to be an hint of a different behaviour with energy in the eclipse. The coronal metal abundances determined with Beppo-SAX are subsolar (~0.2), in line with the results found for many other active stars. |
