vice.yields.ccsne.engines.S16.N20 ================================= N20 core collapse supernova explosion engine as reported by Sukhbold et al. (2016) [1]_. **Signature**: from vice.yields.ccsne.engines.S16 import N20 .. versionadded:: 1.2.0 .. tip:: This object can be passed as the keyword argument ``explodability`` to ``vice.yields.ccsne.fractional`` to calculate IMF-averaged yields assuming this black hole landscape. This object inherits its functionality from the base class ``vice.yields.ccsne.engines.engine`` with the attribute ``frequencies`` assigned according to the N20 explosion engine. See the associated documentation for further details. .. [1] Sukhbold et al. (2016), ApJ, 821, 38
