摘要: We report results from high resolution optical spectroscopy of three non-radiative galactic supernova remnants, RCW 86, Kepler's remnant and SN 1006. have measured the narrow component H-alpha line widths in Balmer-dominated filaments 86 1006, as well width a knot SNR. The SNR show FWHM 30-40 km/s, similar to what has been seen other remnants. Of remnants our sample, 1006 is fastest shock (~3000 km/s). H-beta lines this merely 21 km/s. Comparing sample with those shows that does not correlate simple way velocity. implications for pre-heating mechanism responsible observed are discussed.
