Abstract

Chandra's spectroscopic resolving power allows us to measure velocity shifts down to similar to 30 km/s in line profiles. Observations covering > 2 P(rot) are needed to disentangle flaring and quiescent corona! emission. The rotational modulation in X-ray lightcurves and spectra enable us to estimate the size and location of non-flaring X-ray emitting regions stellar coronae. We probe the coronal structure in systems covering a range of parameters (e.g., spectral type and rotation rate), and summarise results from new studies.
