- W2118045341 abstract "Semi-analytical calculations for the two-body relax- ation in softened potentials are presented and compared with N-body simulations. With respect to a Keplerian potential the increase of the relaxation time in the modied potentials is gen- erallylessthanoneorderofmagnitude,typicallybetween2and 5, if the softening length is of the order of the mean interpar- ticle distance. A comparison between two frequently applied softening schemes, one based on a Plummer mass distribution, the other dened by a spline interpolation on a compact sup- port, shows that the spline-based procedure gives for the same central potential depth systematically smaller increases, but the differences between both are only of the order of 20-40%. If the softening length of the spline based scheme is twice the Plummer softening length, the relaxation rates become almost identical. A simple model that assumes that the influence of softening can be described by neglecting all deflections, if the impact parameter is less than the softening length, and other- wise uses Keplerian orbits, is within a factor of 2 in agreement with the detailed calculations. Measuring the relaxation times by N-body simulations gives a fair agreement with the semi- analytical results and, also with the simple model. In order to reproduce the measured relaxation time ratios the upper limit pmax oftheimpactparameterusedtocalculatetheCoulomblog- arithm must be chosen of the order of the system's size instead ofthemeaninterparticledistancewhichcorroboratestheresults of Farouki & Salpeter (1982, 1994)." @default.
