An analytic solution to the hypersonic, radiative blunt body problem

摘要: We present an analytic model for the thin-shell, radiative interaction between a hypersonic, plane-parallel wind and rigid, spherical obstacle. This problem has clear applications, e.g., to of winds from young stars dense cloudlets, binary partner with photosphere second star. also comparison full, axisymmetric numerical simulation. find only partial agreement simulation model, apparently as result very strong ‘thin-shell’ instabilities post-bow shock flow. Our predicts surface density, flow velocity energy radiated per unit area, well total luminosity bow shock. The can therefore be used directly carrying out comparisons observations different astrophysical objects.
