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]
Bases: object
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.
