Weak Shock Propagation with Accretion. II. Stability of Self-similar Solutions to Radial Perturbations

Eric R. Coughlin, Stephen Ro, Eliot Quataert

Coughlin et al. (2018) (Paper I) derived and analyzed a new regime of self-similarity that describes weak shocks (Mach number of order unity) in the gravitational field of a point…
