Employing a minimum time step. As in Fig. 1, we show the enclosed mass within 10 pc and the energy conservation for various simulations. This time, we investigate how much the simulations are affected when employing a minimum time step. The brighter lines indicate simulations without a minimum time step, i.e. the time step can decrease further. In contrast the darker lines feature a minimum time step of Δt_min = 2.8 × 10⁻⁵ Gyr. The displayed simulations J, N, O, Jt, Nt, and Ot are described in Table A.1.
