Scientific paper

A brief summary is given of the current status and future prospects for X ray observations of stellar coronae. The need for high-throughput high-resolution spectroscopy on fainter and more distant objects (e.g. late-type stars in open clusters of different ages, and in star forming regions) is emphasized. A combination of large effective area (A(eff) approximately 10,000 cm2 at 1 keV) and high spectral resolution (Delta(E) approximately 2 eV at energies > 1 keV and Delta(lambda) approximately 0.03 A at energies < 1 keV) on a telescope with HEW approximately 5 arcsec is required to advance significantly beyond the capabilities of future missions like AXAF, XMM and ASTRO-E.
