Figure 1: 2D surface of equilibrium models for EOS L. The surface is bounded by the nonrotating () and mass-shedding () limits and formed by constant and constant sequences (solid lines). The projection of these sequences in the – plane are shown as long-dashed lines. Also shown are the axisymmetric instability sequence (short-dashed line). The projection of the 2D surface in the – plane shows an overlapping (see dotted lines). (Figure 7 of Stergioulas and Friedman [294].)
