Description

We perform microscopic Molecular Dynamics simulations to study crystallization energetics in the outer crust of Neutron Stars (NSs). We consider the approximation of one component plasma (OCP) and multicomponent plasma (MCP) to take into account contamination for accreting objects. We include Ewald summation techniques for screened interactions to allow a more efficient energy calculation and go beyond previous point-like attemps by using a finite width gaussian ion charge distribution and finite temperature. Our results indicate the crust is less energetically stable under the more realistic picture.
