The Impact of Initial Value on Surface Abundances of Heavy Elements in AGB Stars
摘要/Abstract
摘要:
采用新的s-过程核合成模型和分叉s-过程反应通道,分别取太阳系重元素丰度、太阳系纯r和s-main分量的重元素丰度作初值,计算了太阳金属丰度3M○·TP-AGB星表面重元素丰度.结果表明,不同初值得到不同的表面重元素丰度分布.
Abstract:
Adopting new nucleosynthesis scenario and branch s-process path, we calculated the surface abundances of solar metallicity 3M · ○ TP-AGB star with different initial abundances value : solar heavy element abundances,pure r-process and pure main s-process component of solar heavy element abundances, respectively. The results show that different initial value give inconsistent surface abun-dance of heavy element.
