Low Energy Nuclear Reactions in Late Stellar Evolution

该项目涉及研究和模拟恒星公转后主序星阶段的低能核反应。具体目标是测量红巨星中氦的燃烧方向和渐近巨星中氢和氦的燃烧过程。这些信息对于解释红巨星大气和AGB星周围行星状星云中同位素和元素丰度分布的观测数据是必要的。 这些过程的确定不仅对理解核合成机制很重要，而且对解释这些过程中的快速疏浚和对流过程也很重要。

The project is concerned with the study and simulation of low energynuclear reactions during the post-main sequence phase of stellarevolution. The particular goal is the measurement of helium burningdirection in Red Giant stars and hydrogen and helium burning processes inAsymptotic Giant (AGB) stars. This information is necessary for theinterpretation of observational data on isotopic and elemental abundancedistribution in the atmospheres of Red Giants and in the planetary nebulaesurrounding AGB stars. The determination of these processes is not onlyimportant for the understanding of nucleosynthesis mechanisms but also forthe interpretation of fast dredge-up and convection processes in theseThe experiments are performed at the Notre Dame low energy KN acceleratorwhich is dedicated for nuclear astrophysics measurements.
