贫金属星HD 122956的中子俘获元素丰度

Abundances of the Neutron Capture Elements in Metal Poor Star HD 122956

根据贫金属星ＨＤ１２２９５６的中子俘获元素的观测丰度，利用贫金属星中子俘获元素丰度的计算模型，采用最小二乘法精确地确定了三种不同的中子俘获过程对该贫金属星中子俘获元素丰度的贡献．从理论上预言了贫金属星ＨＤ１２２９５６的中子俘获元素的丰度，并给出了计算结果与观测结果的比较．

Basing on the observed abundances of nertron capture elements in metal poor star HD 122956,combining the model of calculating the elemental abundances in metal poor stars and the method of least square,the contributions from the individual neutron capture processes to the abundances of the neutron capture elements in this metal poor star are determinded accurately.Then the abundances of all the neutron capture elements in HD 122956 are predicted,and the predictions are compared with the observations.
