Wave-Driven Shocks in Stellar Outbursts: Dynamics, Envelope Heating, and Nascent Blastwaves
Christopher D. Matzner, Stephen Ro
We address the shocks from acoustic pulses and wave trains in general one-dimensional flows, with an emphasis on the application to super-Eddington outbursts in massive stars. Usin…
On Linear and Nonlinear Acoustics in Stratified, Variable-Area Ducts and Atmospheres, and Lighthill's Proposition
Christopher D. Matzner, Stephen Ro
We consider linear and nonlinear waves in a stratified hydrostatic fluid within a channel of variable area, under the restriction of one-dimensional flow. We derive a modified vers…
Weak Shock Propagation with Accretion. III. A Numerical Study On Shock Propagation & Stability
Stephen Ro, Eric R. Coughlin, Eliot Quataert
Core-collapse supernovae span a wide range of energies, from much less than to much greater than the binding energy of the progenitor star. As a result, the shock wave generated fr…
The Wolf-Rayet Stellar Response To The Iron Opacity Bump: Envelope Inflation, Winds, and Microturbulence
Stephen Ro
Early-type Wolf-Rayet(WR) stellar models harbor a super-Eddington layer in their outer envelopes due to a prominent iron opacity bump. In the past few decades, one-dimensional hydr…
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…
Weak shock propagation with accretion. I. Self-similar solutions and application to failed supernovae
Eric R. Coughlin, Eliot Quataert, Stephen Ro
We present solutions for the self-similar propagation of a shock wave in a hydrostatic, adiabatic medium with a point mass gravitational field. In contrast to the well-known, Sedov…
