Schematic diagram of the Hénon method. The cumulative velocity change due to many two-body encounters in a realistic cluster can be calculated given the average local mass, velocity, and density of stars with Equation (9). In Hénon’s method, this is reduced to a single encounter between nearest-neighbor particles, where the deflection angle is chosen to reproduce the statistical predictions using Equation (12).
