vice.yields.ccsne.engines.E16.intercept

Type : float [default : 0.043]

The intercept of the line in \(\mu_4-M_4\mu_4\) space dividing progenitors which explode and collapse. Ertl et al. (2016) [1] argue that the quantities \(M_4\) and \(\mu_4\) can predict whether or not a massive star will produce a core collapse supernova based on the following criterion with only a few exceptions (~1 - 2.5%):

\[\mu_4 \leq a M_4 \mu_4 + b\]

where this attribute encodes the value of \(b\).

Example Code

>>> from vice.yields.ccsne.engines import E16
>>> E16.intercept
0.043
>>> E16.intercept = 0.04
>>> E16.intercept
0.04
>>> E16.intercept = 0.045
>>> E16.intercept
0.045
