Scientific paper

We propose an LETG/HRC-S observation of the bright, eclipsing contact binary 44i Boo to map coronal structures at different temperatures. This 120 ks observation will complement the 60 ks archival HETG oservation, which shows rotationally broadened line profiles and line centroid shifts as a function of orbital phase. This emission appears to be related to polar starspots found in optical Doppler images of rapid rotators. Given the short period of 44i Boo (6.4 hr), and the high spectral resolution at long wavelengths of LETG, the emission lines from a localized active region will exhibit observable line profile changes. The LETG/HRC-S spectra will provide line shift measurements, light curves, and diagnostics for temperature, density, and elemental abundances.
