Fig. 5


Dimensionless mass as a function of the cut-off parameter α for (solid line), 0.5 (dashed line), 0.8 (dotted lines), 1.3 (dash-dotted line). The discontinuity of the curves for some values of the cut-off parameter arises because the condition RRΛ that is necessary for the existence of the equilibrium configurations is not fulfilled (see Figs. 13 and Eqs. (62), (63)).
