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 Hα line widths in Balmer- dominated filaments 86 1006, as well width a Balmer-dominated knot SNR. The SNR show FWHM 30−40 km s −1 , similar to what has been seen other remnants. Of remnants our sample, 1006 is fastest shock (∼3000 ). Hβ lines this merely 21 . Comparing sample with those shows that does not correlate simple way velocity. implications for pre-heating mechanism responsible observed are discussed.
