pynucastro.eos.degeneracy_parameter_bounds module#

A coarse table of degeneracy parameter (eta) for use in bracketing the root finding algorithm.

pynucastro.eos.degeneracy_parameter_bounds.get_eta_bounds(rhoYe0, T0, include_positrons=True)[source]#

Return an interval that we expect to contain the degeneracy parameter, eta, given a rho * Ye and T

Parameters:
  • rhoYe0 (float) – the electron mass fraction (rho * Ye)

  • T (float) – the temperature (K)

Return type:

tuple(float, float)
