Scientific paper

Deep Chandra X-ray Observatory high energy transmission grating {HETGS} exposures of three key G0-G5 giants will address fundamental questions concerning their hot magnetized coronae by determining temperatures and densities, probing chemical fractionation processes, and exploring plasma dynamics. The giants lie in or near the "Rapid Braking Zone" where moderate mass stars undergo a radical transformation of their outer atmospheres, perhaps as a relic magnetosphere is disrupted by the onset of a solar-like dynamo. These are ideal targets to exploit the experience gained in the CXO "Emission Line Project" studies of the active binaries Capella and HR 1099. For two of the targets-31 Comae and Mu Velorum-we will obtain contemporaneous medium-resolution far-UV echelle spectra using the HST/STIS E140M mode for 3 orbits each. The far-UV spectra will provide a snapshot of the physical state of the subcoronal atmosphere during each long X-ray grating exposure, and will tie directly into the 2-25 A HETGS spectra by recording the key Fe XXI 1354 A coronal forbidden line.
