Table 1
Initial period P, ratio between the dust formation radius and the Roche-lobe radius, Rd/RL,1, and accretion efficiency βacc for binary systems with a 1.0 M⊙ AGB primary and a 0.6 M⊙ main-sequence companion (from Mohamed 2010).
| P /days | Rd/RL,1 | βacc |

| 1.34 × 105 | 0.40 | 0.10 |
| 5.98 × 104 | 0.67 | 0.24 |
| 2.58 × 104 | 1.18 | 0.45 |
| 9.12 × 103 | 2.4 | 0.35 |
| 3.21 × 103 | 2.8 | 0.10 |
Notes.Because RL,1 ∝ a (and Rd does not depend on a), high values of the Rd/RL,1 ratio correspond to close systems and low values correspond to wide systems.
