| Abstract: |
The LECS instrument on-board the SAX X-ray observatory, thanks to its unprecedented combination of wide band (from 0.1 to 10.0 keV) and spectral resolution (comparable to that of CCD based detectors at low energies) allows a fresh look into the X-ray emission from stellar coronal sources. We discuss the first SAX-based observations of coronal sources, with data from the giants Capella and beta Cet, the active binaries VY Ari and HD 9770, and from the flare star AD Leo. The coronal temperature stratifications implied by the data are discussed, as are the derived coronal abundances, which are compared to the available photospheric abundances of the emitting stars. |
