Stellar parameters
$L = \sigma \cdot 4 \cdot \pi \cdot R^2 T^4$
Input 2 of the 3 parameters, the 3rd one is calculated.
Wind parameters
$R_\text{t} = R \cdot \left(\left.\frac{v_\infty}{2500\,\text{km}/\text{s}} \right/
\frac{\dot{M} \sqrt{D}}{10^{-4}\,M_\odot / \text{a}} \right)^{2/3}$
→ transformed radius (see
Schmutz, Hamann & Wessolowski 1989 )
$\displaystyle\eta = \dot{M} \cdot \frac{v_\infty}{L/c}$ → wind efficiency
Input R, v∞, log $\dot{M}$, D to calculate → Rt and log Rt.
OR:
Input R, v∞, D and Rt or log Rt to calculate → log $\dot{M}$.
OR:
Input v∞, log $\dot{M}$, log L to calculate → η.
