Public Algorithm Evaluating the Nucleosinthesis of Primordial Elements

PArthENoPE is a FORTRAN77 numerical code which computes the abundances of light nuclides produced during Big Bang Nucleosynthesis. Starting from nuclear statistical equilibrium conditions the program solves the set of corresponding coupled ordinary differential equations, follows the departure from chemical equilibrium of nuclear species, and determines their asymptotic abundances as function of several input cosmological parameters as the baryon density, the number of effective neutrino species, the value of cosmological constant and the neutrino chemical potential.

The most recent version is PArthENoPE 2.0 (December 13, 2017), WHICH WILL BE DISTRIBUTED AS SOON AS POSSIBLE, AFTER PUBLICATION OF THE REFERENCE PAPER. In the meantime, the most recent distributed version is PArthENoPE 1.10 (January 27, 2017).
