低Z元素在太阳整个预测寿命期间的丰度研究

A Study of the Abundance of Low-Z Elements in the Sun During its Whole Predicted Life

M. H. Talafha, M. A. Al-Wardat, N. M. Ershidat

摘要:

研究恒星和星系的元素组成是了解它们起源和演化的关键课题。在这项研究中,我们提出了在太阳生命的四个阶段,氢燃烧,快速增长和红巨星的开始,氦燃烧和氦耗尽的同位素$^{1}$ H,$^{4}$ He,$^{12}$ C,$^{14}$ N,$^{15}$ O,$^{16}$ O,$^{17}$ O和$^{18}$ O的太阳丰度的计算结果。美国南卡罗来纳州克莱姆森大学Webnucleo集团的开源软件包nucnet-tools用于此目的。所有同位素的结果都列在表格中供将来使用。丰度发现,全球范围内,同意相当不错,在文献中预测。最后两个阶段取得的成果在其他地方没有同等的成果。

英文摘要:

The study of the elemental composition of stars and galaxies is a key topic for understanding their origin and evolution. In this study, we present the results of the calculation of solar abundances of the isotopes $^{1}$H, $^{4}$He, $^{12}$C, $^{14}$N, $^{15}$O, $^{16}$O, $^{17}$O, and $^{18}$O during the four phases of the solar life; Hydrogen burning, Onset of rapid growth and red giant, Helium burning and Helium exhaustion. The open source package nucnet-tools from the Webnucleo Group in Clemson University, SC, USA was used for this purpose. The results for all isotopes are listed in tables for future use. Abundances found, globally, agree fairly well with those predicted in the literature. Results obtained for the last two phases have no equivalent elsewhere.
