Modeling W44 as a Supernova Remnant in a Density Gradient with a Partially Formed Dense Shell and Thermal Conduction in the Hot Interior. II. The Hydrodynamic Models
In a previous paper, we presented the analytical background for a new model for W44; in this paper, we report hydrocode experiments verifying many of the details. Our model remnant is evolving in a moderately dense (~6 cm-3), ambient medium having a substantial density gradient. At the observed age (~20,000 …
