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…
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…
Pre-Supernova Outbursts via Wave Heating in Massive Stars II: Hydrogen-poor Stars
Jim Fuller, Stephen Ro
Pre-supernova (SN) outbursts from massive stars may be driven by hydrodynamical wave energy emerging from the core of the progenitor star during late nuclear burning phases. Here,…
Shock Dynamics in Stellar Outbursts: I. Shock formation
Stephen Ro, Christopher D. Matzner
Wave-driven outflows and non-disruptive explosions have been implicated in pre-supernova outbursts, supernova impostors, LBV eruptions, and some narrow-line and superluminous super…
On the Launching and Structure of Radiatively Driven Winds in Wolf-Rayet Stars
Stephen Ro, Christopher D. Matzner
Hydrostatic models of Wolf-Rayet stars typically contain low-density outer envelopes that inflate the stellar radii by a factor of several and are capped by a denser shell of gas.…
Oblique Shock Breakout in Supernovae and Gamma-Ray Bursts: II. Numerical Solutions For Non-Relativistic Pattern Speeds
Pegah Salbi, Christopher D. Matzner, Stephen Ro +1
Non-spherical explosions develop non-radial flows as the pattern of shock emergence progresses across the stellar surface. In supernovae these flows can limit ejecta speeds, stifle…
