vice.singlezone.Z_solar¶
Type : real number
Default : 0.014
The metallicity by mass of the sun \(M_Z/M_\odot\). This is used in calibrating the total metallicity of the ISM, which is necessary when there are only a few elements tracked by the simulation with metallicity dependent yields. This scaling is implemented as follows:
where the summation is taken over the elements tracked by the simulation.
Note
The default value is the metallicity calculated by Asplund et al.
(2009) [1]; VICE by default adopts the Asplund et al. (2009)
measurements on their element-by-element basis in calculating [X/H]
and [X/Y] in simulations. Users who wish to adopt a different model
for the composition of the sun should modify both this value
and the element-by-element entires in vice.solar_z.
Example Code¶
>>> import vice
>>> sz = vice.singlezone(name = "example")
>>> sz.Z_solar = 0.014
