Type : float
Default : 1.7
The power-law index of the \(\dot{\Sigma}_\star - \Sigma_\text{gas}\)
relation at gas surface densities \(\Sigma_\text{gas} \leq
\Sigma_{\text{gas},1}\), where \(\Sigma_{\text{gas},1}\) is the
value of the attribute Sigma_g1
.
Example Code¶
>>> import vice
>>> mw = vice.milkyway(name = "example")
>>> mw.zones[0].tau_star.index1
1.7
>>> for i in range(mw.n_zones):
>>> mw.zones[i].tau_star.index1 = 1.5
>>> mw.zones[0].tau_star.index1
1.5
