    5 As shown in Figure 1, Astrobear interpolates between the progenitor density profile (red diamonds, Fig. 1) to arbitrary positions on the mesh (i.e. cell centers, blue curve). After feeding the progenitor density profile through the HSE numerical integrator (to compute an HSE pressure profile for supplied density profile and external pressure), AstroBEAR interpolates the calculated HSE pressure  profile onto the grid (Fig. 2). The values of the ambient medium are just the constant progenitor profiles beyond a radius containing 3 solar masses ($r=7.26 e+9 ~cm$).
