vice.singlezone.schmidt¶
Type : bool
Default : False
If true, the simulation will adopt a gas-dependent \(\tau_*\). At each timestep, the star formation efficiency timescale is determined via:
where \(\tau_{*,\text{specified}}(t)\) is the value of the attribute
tau_star
, \(M_g\) is the mass of the interstellar medium,
\(M_{g,\text{Schmidt}}\) the normalization thereof (attribute
MgSchmidt
), and \(\alpha\) the power-law index set by the
attribute schmidt_index
.
This is an application of the Kennicutt-Schmidt star formation law to the single-zone approximation (Kennicutt 1998 1; Schmidt 1959 2, 1963 3).
If False, this parameter does not impact the star formation efficiency that the user has specified.
