Abstract

The mechanism which excites the optical emission in the knots of fast-moving oxygen-rich ejecta found in young supernova remnants is generally assumed to be the propagation of a slow, radiative, reverse shock into them. This paper investigates the structure and emission spectra of such shocks, extends the results of Itoh (1981) by the inclusion of elements other than oxygen, and compares the results with observations. It is concluded that the fit between theory and observation is poor, and alternative interpretations for modeling are suggested.
