The evolution of binary mass ratios and semimajor axes in the same simulations shown in Figure 2. At larger mass ratios, we find results in general agreement with previous studies. However, at intermediate mass ratios, which have not been previously probed at ﹩{ \mathcal M }\ne 10﹩, we find extremely rapid inspirals, following from both the appreciably negative torque, small specific angular momentum of the binary and that λ > q. At very low mass ratios (q ≲ 0.03), the rate of change of the binary semimajor axis can be quite large unless the torque is very nearly balanced by the change in the mass of the binary. Numerical values are provided in Table 4.
