vice.yields.ccsne.engines

Core collapse supernova explosion engines: explodability as a function of progenitor mass in solar masses.

Signature: from vice.yields.ccsne import engines

New in version 1.2.0.

Tip

Instances of the engine class can be passed as the keyword argument explodability to vice.yields.ccsne.fractional to calculate IMF-averaged yields assuming a particular black hole landscape. The impact of these assumptions is explored in Griffith et al. (2021) 1.

Contents

enginetype

The base class implemented in this module.

cutoffengine

An engine characterized by a threshold mass, below which stars explode as CCSNe, and above which stars collapse directly to a black hole.

E16engine

An engine implementing the Ertl et al. (2016) 2 model, characterized by the two parameters \(M_4\) and \(\mu_4\).

S16module

Explodability maps as reported by the various models in Sukhbold et al. (2016) 3.
