摘要
将解释s+r星元素丰度的单辐照和对流2种参数化模型的最佳拟合参数进行了对比,找出了这些参量的分布规律以及各参量之间的关系,得到了s-过程和r-过程核合成相关信息,进一步确定了s+r星的主要形成机制.还对文献[13]做了有益的补充,给出了单辐照模型r-过程分量系数与s-过程分量系数之间的关系图.
By comparing the best-fit parameters of the two models which explain the observed abundances of s + r stars: single neutron-exposure model and convectional model, the distributing law and the relations of the parameters were found and more information on nucleosynthesis of s-process and r-process was also obtained. Therefore,the main formation mechanism of s + r stars gets further confirmed. Meanwhile, the graph about the relationship between the component coefficients of the s-process and r-process is also presented, which is an constructive supplement to literature.
