Next: Initial conditions Up: Old neutron star distribution Previous: Introduction . The problem to be solved is to find stationary space distribution of stars which have had certain initial space and velocity distributions and move in a given potential. ... In principle, the most straightforward way to obtain the solution is to integrate directly the equations of motion for a sufficiently large number of stars with different initial conditions. ... Then space density is given by . ...
