Query: A Study of the Coronal Plasma in RS CVn binary systems   XMM-Newton has been performing comprehensive studies of X-ray bright RS CVn
binaries in its Calibration and Guaranteed Time programs. We present results
from ongoing investigations in the context of a systematic study of coronal
emission from RS CVns. We concentrate in this paper on coronal abundances and
investigate the abundance pattern in RS CVn binaries as a function of activity
and average temperature. A transition from an Inverse First Ionization
Potential (FIP) effect towards an absence of a clear trend is found in
intermediately active RS CVn systems. This scheme corresponds well into the
long-term evolution from an IFIP to a FIP effect found in solar analogs. We
further study variations in the elemental abundances during a large flare.
