  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.
