Thermal equilibrium curves in the Σ − Tmid(−Teff) plane for different magnetic field configurations. From top to bottom, first panel: result of S18 (circles) with outflow conditions with new additional simulations using a zero net magnetic field configuration, second panel: Bz0 = 0.8 G, third panel: Bz0 = 2 G, last panel: Bz0 = 8 G. The colors of the dot correspond to the value of α. Triangles show the instability points where the patch of disk undergoes critical cooling (downward-pointing triangle) or heating (upward). Stars indicate the simulations from the middle branch that did not converge. Gray vertical lines are plotted at the end of the hot and cold branch to facilitate comparisons between the panels. Finally, the colored S-curves in solid lines shows the DIM model with convection using different values for α.
