Notes.N is the number of orbits over which the values are averaged after the quasi-steady state is reached. βsink is the averaged mas-accretion efficiency measured from the net sink inflow. β0.4RL,2 is the averaged mass-accretion efficiency measured from the net inflow into a shell of radius 0.4RL,2, i.e. it includes the mass inflow of the sink and of the accretion disk, if present. βBHL corresponds to the mass accretion efficiency as predicted by BHL (Eq. (5)) with αBHL = 1. η is the averaged specific angular momentum of material lost. Rdisk is the approximate radius of the disk in AU after eight orbital periods, except for model V10a5, where the radius corresponds to 2 orbital periods. Mdisk is the mass within Rdisk. ȧ/a is the relative rate of change of the orbit as derived from Eq. (3) in units of yr−1. Positive sign means the orbit is expanding, whereas negative sign means that the orbit is shrinking
