Public Algorithm Evaluating the Nucleosynthesis 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, with the implementation of the recently calculated rate of the reaction D + p → γ + 3He (Nature 587 (2020) 210-213) and an improved GUI, is PArthENoPE 3.0 (March 10, 2021), which will be distributed with the publication of the corresponding reference paper.
