  We have been conducting a comprehensive survey of stellar coronae with the
XMM-Newton Reflection Grating Spectrometers during the commissioning,
calibration, verification, and guaranteed time phases of the mission,
accompanied by simultaneous observations with the EPIC cameras and, for several
targets, with the radio VLA and/or the VLBA. The principal aim of this project
is threefold: i) To understand stellar coronal structure and composition by
studying systematics in the coronae of stars with widely different levels of
magnetic activity; ii) to investigate heating and particle acceleration physics
during flares, their role in the overall coronal energy budget, and their
possible role in the quiescent stellar emission; iii) to probe stellar coronal
evolution by studying solar analogs of different ages. We report early results
from this project.
