# Three-dimensional hydrodynamic instabilities in stellar core collapses

@article{Lou2011ThreedimensionalHI, title={Three-dimensional hydrodynamic instabilities in stellar core collapses}, author={Yu-qing Lou and Biao Lian}, journal={Monthly Notices of the Royal Astronomical Society}, year={2011}, volume={420}, pages={2147-2161} }

A spherically symmetric hydrodynamic stellar core collapse process under gravity is time-dependent and may become unstable once disturbed. Subsequent non-linear evolutions of such growth of hydrodynamic instabilities may lead to various physical consequences. Specifically for a homologous collapse of a stellar core characterized by a polytropic exponent Γ= 4/3, we examine oscillations and/or instabilities of three-dimensional (3D) general polytropic perturbations. Being incompressible, the…
