pynucastro.neutrino_cooling.sneut5_mod module#

Classes and methods that implement the Itoh et al. 1996 thermal neutron loss terms.

class pynucastro.neutrino_cooling.sneut5_mod.NeutrinoComponents[source]#

A simple container that holds the individual components to the neutrino cooling.

pynucastro.neutrino_cooling.sneut5_mod.ifermi12(f)[source]#

Apply a rational function expansion to get the inverse fermi-dirac integral of order 1/2 when it is equal to f.

The maximum error is 4.19e-9_rt (see Antia ApJS 84,101 1993)

pynucastro.neutrino_cooling.sneut5_mod.sneut5(rho, T, comp=None, *, abar=None, zbar=None, full_output=False)[source]#: Compute thermal neutrino losses from the analytic fits of Itoh et al. ApJS 102, 411, 1996. Note that either a Composition object of abar/zbar need to be provided.
