We propose to observe the coronal emission from twosupermetalrich (SMR) latetype stars, in order to determine theplasma emission measure distribution vs. temperature, and individualelement abundances, from the analysis of EPIC and RGS spectra.These observations, will help to test current hypotheses about the linkbetween photospheric and coronal abundances, and the possiblerelationship between activity level and metal depletion in stellarcoronae. The characteristics of the coronal structures will be alsostudied by means of direct plasma density estimates from Helike triplets. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
