Fit parameters for main-sequence lifetime of stars.
| Z [Z⊙] | b0 | b1 | b2 | b3 | x0 |
|---|---|---|---|---|---|
| ≤10−8 | 9.88 | −3.78 | 1.41 | −0.19 | 2.70 |
| 0.028 | 10.10 | −3.78 | 1.26 | −0.14 | 2.08 |
| 0.28 | 10.34 | −4.20 | 1.49 | −0.17 | 2.08 |
| 0.56 | 10.39 | −4.28 | 1.51 | −0.17 | 2.08 |
| 1.41 | 11.00 | −5.72 | 2.52 | −0.39 | 2.08 |
| ≥3.52 | 11.19 | −6.51 | 3.11 | −0.51 | 2.08 |
Notes. We adopt the Portinari et al. (1998) model for Pop. II stars and the S02 model for Pop. III (
) stars. We use the fit formula of Eq. 8 fixing b4 = 0. The unit of main-sequence lifetime is [yr].
