Dependence of the critical rotation period P_c (top panel), relative increase in total angular momentum ∆L/L (middle panel), and free energy ∆E_f /E_f (bottom panel) on the ratio of the cohesive force F_c to gravity force F_g. Both gains are related to the current values of the quantities. The lines end at the ratio value for which the orbital energy of the system becomes positive after fission. The violet, blue, and yellow lines indicate A_R equal to 0.07, 0.05, and 0.10 (cases 1, 2, and 3 in Table 2) whereas the red line is for case 6. Diamonds show the initial lobe configuration TA − TB and squares mean SA − SB merger. Symbols are placed where values of the cohesive to gravity force ratio correspond to the cohesive strength of 50, 100, 200, 400, 700, and 1000 Pa for the assumed value of the neck cross-sectional area.
