vice.singlezone.MgSchmidt

Type : real number

Default : 6.0e+09

The normalization of the gas supply in \(M_\odot\) when star formation efficiency is dependent on the gas supply:

\[\tau_\star \sim \left(\frac{M_g}{M_{g,\text{Schmidt}}}\right)^{-\alpha}\]

where \(\alpha\) is specified by the attribute schmidt_index.

Note

This attribute is irrelevant when the attribute tau_star is a function of two variables.

Tip

In practice, this quantity should be comparable to a typical gas supply of the simulated zone so that the actual star formation efficiency at a given timestep is near the user-specified value.
