Numerical Investigation of Non-Homologous Collapse of the One-Dimensional Gravitational Gas

Kim Gargar, Jose Perico Esguerra


In this paper, the one-dimensional gravitational gas is evolved numerically using an eventdriven code. Two initial conditions are considered: (1) an initially uniform isolated system with no velocity dispersion and where the initial velocities are sine functions of the position, and (2) two “clusters” with initially constant phase-space densities in elliptical regions of phase space.
