摘要 采用与Tsujimoto类似的方法,根据观测到的极贫金属星中各元素与Si丰度的相关性,利用WW95和FM2004给出的Ⅱ型超新星Si的理论产量,计算了极贫金属环境中各种质量超新星α-元素,铁族元素的产量,并将所得结果与前人的结果进行了比较。 Adopting the same method as Tsujimoto used, this paper calculates the a-element and Fe-group element yields of SNe Ⅱ with various masses from the latest observed element abundance and the theoretical yield of Si given by WW95 and FM2004. The previous results and results obtained in this paper are also compared.
