Orbital evolution examples for conservative (top four panels) and non-conservative (bottom four panels) MT. For the latter, β = 0.2 for the polytrope, J1e, J3e, and J10e, and β = 0.4 for J3ei, while α = 1. The different models are identified by color and line style on the left (as in Figure 2) and color on the right. The black lines are for the polytrope. Each set of four panels on the left are P_orb (top) and M_pl (bottom), while on the right are the timescales for the evolution of a (top) and M_pl (bottom) due to MT (dotted lines) and tides (solid lines).
