Abstract
Emission line ratios of unsteady radiative shocks are shown to be indistinguishable from those of steady shocks with velocities about 100 km s-1, although shock parameters such as velocity and preshock density are significantly different. If the shocks are radiatively unstable, then it may be possible to observe time variations of line ratios in SNRs over a period of a few years.
