vice.elements.yields.sneia

Type : real number or <function>

The current yield setting for type Ia supernovae (SNe Ia). If this is a real number, it will be interpreted as a constant, metallicity-independent yield. If it is a function, it must accept the metallicity by mass \(Z\) as the only parameter.

These values can be calculated by calling vice.yields.sneia.fractional.

Note

Modifying yield settings here is equivalent to modifying vice.yields.sneia.settings.

Example Code

>>> import vice
>>> vice.elements.Fe.yields.sneia = 0.0017
>>> vice.elements.O.yields.sneia = 0
>>> def z_dep_fe_yield(z):
        return 0.0017 * (z / 0.014)**0.5
>>> vice.elements.Fe.yields.sneia = z_dep_fe_yield
