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

TL;DR

This paper calculates the abundances of low-Z isotopes in the Sun throughout its life cycle, using open-source tools, providing data that aligns with existing predictions and offering new insights for later stellar phases.

Contribution

It presents detailed solar isotope abundance calculations across all life phases, including the last two phases which lack prior data.

Findings

Abundances agree with literature predictions.

Provides data for the Sun's last two life phases.

Uses open-source computational tools.

Abstract

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.
