Currently, one of the most important unanswered questions in astrophysics and nuclear astrophysics is the “Lithium problem”, which refers to the mismatch between the experimental and theoretical values of lithium abundance in Big-Bang nucleosynthesis. Finding a solution for this problem and making a match between these two values can be another proof to one of three pillars of the Big Bang theory, and can also help to improve the calculating method of the existing nuclei abundance. One of the newest used methods so as to calculate the reaction rates is the Bayesian method. This study focuses on the details of the Bayesian statistics application in astrophysical calculations, and a narrative review of all the performed studies in this field is presented, as well. This study, after reviewing all the studies in this field, considers the mentioned method as a new method for reaction rate and nuclei cross-sectional calculations, which leads to small but valuable improvements in the results of the previous calculations.

核天体物理反应速率和不确定性的贝叶斯计算综述

目前,天体物理学和核天体物理学中最重要的未解决问题之一是“锂问题”,即大爆炸核合成中锂丰度的实验值和理论值之间的不匹配。为这个问题找到一个解决方案并在这两个值之间进行匹配,可以再次证明大爆炸理论的三大支柱之一,也可以帮助改进现有原子核丰度的计算方法。用于计算反应速率的最新使用方法之一是贝叶斯方法。本研究侧重于贝叶斯统计在天体物理计算中的应用细节,并对在该领域进行的所有研究进行了叙述性回顾。本研究在回顾了该领域的所有研究后,
