PArthENoPE revolutions

This paper presents the main features of a new and updated version of the program PArthENoPE, which the community has been using for many years for computing the abundances of light elements produced during Big Bang Nucleosynthesis. This is the third release of the PArthENoPE code, after the 2008 and the 2018 ones, and will be distributed from the code's website, http://parthenope.na.infn.it. Apart from minor changes, the main improvements in this new version include a revisited implementation of the nuclear rates for the most important reactions of deuterium destruction, 2H(p,γ)^3 He, 2H(d, n)^3 He and 2H(d, p)^3 H, and a re-designed GUI, which extends the functionality of the previous one. The new GUI, in particular, supersedes the previous tools for running over grids of parameters with a better management of parallel runs, and it offers a brand-new set of functions for plotting the results.

本文介绍了PArthENoPE程序全新更新版本的核心特性。该程序已被国际学界广泛使用多年，用于计算大爆炸核合成（Big Bang Nucleosynthesis）过程中产生的轻元素丰度。此为PArthENoPE代码的第三个正式发行版，前两个版本分别发布于2008年与2018年，将通过该代码的官方网站http://parthenope.na.infn.it 对外分发。除若干细微调整外，该新版本的核心改进主要包含两部分：一是对氘（deuterium）销毁的关键反应核反应率进行了重新实现，具体涉及²H(p,γ)³He、²H(d, n)³He与²H(d, p)³H这三类核心反应；二是重新设计了图形用户界面（Graphical User Interface, GUI），拓展了旧版界面的功能。具体而言，新版GUI取代了过往用于参数网格扫描的运行工具，可实现更高效的并行任务管理；同时还提供了一套全新的结果绘图功能。
