Figure 2.
The critical line ξc(ω) (equation (4.5)) and a set of planets (§5) plotted in parameter space. Above the critical line two LEB solutions exist. Below the critical line no LEB solutions exist. MAF solutions exist at all points in parameter space. MEP solutions are identical to the LEB solutions above the critical line and identical to the MAF solution below the critical line. The rotation line (ω = 1) separates planets with ‘high’ rotation rate from planets with ‘low’ rotation rates (solid line, critical line; grey dotted line, rotation line; filled circle, Earth; open circle, Mars; filled square, Venus; open triangle, Titan; filled triangle, P1).
