Stellar and wind parameters used in the fast wind test.
| Name | Parameter | Value |
|---|---|---|
| Mass-loss rate | Ṁ | 10−6 M⊙ yr−1 |
| Terminal wind velocity | υ∞ | 700 km s−1 |
| Initial wind velocity | υ0 | 100 km s−1 |
| Stellar mass | M* | 20 M⊙ |
| Stellar radius | R* | 30 R⊙ |
| Stellar luminosity | L* | 100 000 L⊙ |
| Stellar surface temperature | T* | 20 000 K |
| Escape velocity at R* | υesc(R*) | →504.5 km s−1 |
| Wind timestep | twind | 0.02 days |
| End time | tend | 5 days |
| SPH particle mass | MSPH | 10−11 M⊙ |
| Particles per shell | Nshell | →∼5 |
| Particles in simulation | Ntot | →∼1378 |
| Median smoothing length | h | →∼32 R⊙ |
Notes. Derived parameters are indicated with an arrow (→). Since the smoothing length is highly variable with extreme outliers, we include the median value of all gas particles shown in Fig. 4.
