Our understanding of the structure of radiative shocks of modest (vs ≲ 200 km s−1) velocity has improved greatly since the pioneering work of Cox (1972). This advance has been accomplished primarily by a more complete development of the physics of the shock front, its ionisation precursor and of the cool recombination zone. (Dopita 1976, 1977; Raymond 1979; Shull and McKee 1979; Shull, Seab and McKee, this conference; D'Odorico and Dopita, this conference). However, all models used for spectrum synthesis have so far involved one dimensional steadyflow hydrodynamics and most have covered only a very limited range in parameter space. This has meant that whilst they can be used to estimate shock velocities and metallicities of the (assumed) fully radiative shocks found in nearby SNRs, they are of limited applicability in more exotic types of objects.
