XMM reflection grating spectroscopy of low and medium activity stars

We propose to obtain XMM RGS spectra of a sample of low and medium activitymain sequence stars. The sample is chosen in such a way as to coverdifferent states of activity and spectral types. We aim at detecting theOVII triplett at 22 Angstrom with at least 500 counts in the line and atdoing plasma spectroscopy using the OVII forbidden line. In addition weplan to study the coronal temperatures using the OVIII to OVII line ratiosand coronal abundances.
