Notes. The metallicity (Z) of all simulations is initially set to 0.001, and we define the concentration parameter as the ratio of the initial half-mass radii for the two populations $(r_{h}^{P 2} / r_{h}^{P 1}) . F^{P 2}$ $Mathematical equation: $\left(r_{\mathrm{h}}^{\mathrm{P} 2} / r_{\mathrm{h}}^{\mathrm{P} 1}\right). F^{P 2}$$ is the fraction of the total number of objects (single or binary stars) in the P2 population.
