The Antesonic Condition for the Explosion of Core-Collapse Supernovae II: Rotation and Turbulence

In the model problem of steady spherical pressure-less free-fall onto a standing shockwave around an accreting central mass, the "antesonic" condition limits the regime of stable accretion to ${c\_T^2/v\_{\rm esc}^2\leq3/16}$, where $c\_T$ is the …

The antesonic condition for the explosion of core-collapse supernovae - I. Spherically symmetric polytropic models: stability and wind emergence

Shock revival in core-collapse supernovae (CCSNe) may be due to the neutrino mechanism. While it is known that in a neutrino-powered CCSN, explosion begins when the neutrino luminosity of the protoneutron star exceeds a critical value, the physics of …

Accurate, meshless methods for magnetohydrodynamics

Recently, we explored new meshless finite-volume Lagrangian methods for hydrodynamics: the "meshless finite mass" (MFM) and "meshless finite volume" (MFV) methods; these capture advantages of both smoothed particle hydrodynamics (SPH) and adaptive …
