Angular momentum relaxation timescales ﹩{T}_{j}=1/{D}_{{jj}}^{\mathrm{iso}}﹩ by RR (solid line), and by two-body relaxation (NR; dashed line), as a function of semimajor axis. Relaxation by RR is faster than two-body relaxation in a limited range of semimajor axis. For comparison, we show the main sequence ages of some of the S-stars estimated recently by Habibi et al. (2017; red circles with error bars) and the vector RR timescale (dotted line). The cusp’s parameters are the same as in Figure 1.
