sequence onward calculated in vplanet using the eqtide and stellar modules.
Orbital eccentricity evolution is given by the red solid line, the orbital
period by the purple dashed line, and the ratio of stellar rotation rate to
-binary mean motion ($\Omega/n$) evolution is given by the blue dot dashed curve.
+binary mean motion (Omega/n) evolution is given by the blue dot dashed curve.
The binary's evolution qualitatively agrees with that of an identical system
presented in Figure 1 of :cite:`ZahnBouchet89`.
