Physical parameters adopted in our binary population models.
| Model set | Physical parameters |
| (differences from model set A) | |
|
|
|
| A | Default |
| A1 | [C/Fe] > 1.0 |
| A4 | As A1, log 10(g/ cm s-2) < 4.0, no luminosity selection |
| B | Angular-momentum loss: ΔJ/J = 2 (ΔM/M) |
| Wind-accretion efficiency: BHL, αBHL = 10 | |
| (as model B of Papers I and II) | |
| C | Angular-momentum loss: ΔJ/J = 2 (ΔM/M) |
| Wind-accretion efficiency: WRLOF | |
| (as model C of Paper II) | |
| D | No thermohaline mixing |
| IK01 | Multiple-part power-law IMF (Kroupa 2001), |
| for M> 1 M⊙, IMF slope is less steep than default. | |
| IL05 | Log-normal IMF (Lucatello et al. 2005), |
| μlog M = 0.79,σlog M = 1.18. | |
| Q1 | φ(q) ∝ q |
| Qp4 | φ(q) ∝ q-0.4 |
| SDM | Log-normal initial-period distribution |
| (Duquennoy & Mayor 1991), μlog P = 4.8,σlog P = 2.3. | |
| S3 | As SDM with μlog P = 3.0 |
| T8 | tmin = 8 Gyr |
| T12 | tmin = 12 Gyr |
