【摘要】：根據(jù)觀測(cè)到的極貧金屬星中元素Sr,Y,Ba與元素Si豐度的相關(guān)性,利用WW1995與FM2004給出的Ⅱ型超新星Si的理論產(chǎn)量計(jì)算了極貧金屬環(huán)境下各種質(zhì)量超新星r-過程元素的核合成產(chǎn)量,將所得結(jié)果與前人的結(jié)果作了對(duì)比;進(jìn)一步討論了星系化學(xué)演化中r-過程元素核合成的主要產(chǎn)量區(qū)間.
[Abstract]:Based on the observed correlation between element Sr,Y,Ba and element Si abundance in extremely poor metal stars, the nuclear synthesis yields of elements of various mass supernova r-process elements in extremely poor metal environment are calculated by using the theoretical output of type 鈪，
