The Metallicity of the Sun Reviewed from Pre-Main Sequence Evolution

Metallicity is defined as the fraction of abundance elements heavier than hydrogen and helium. has different values for stellar objects its value will also change star evolves. This research focused on calculating analyzing early metallicity Sun, that at beginning Sun's evolution Pre-Main Sequence. Five samples with an initial mass 1 M ⊙ were used. study uses code MESA r-15140 which produces a Hertzsprung-Russell diagram various metallicities. From simulation, it found most suitable 0.065. There are four dominant core namely hydrogen, helium, carbon, oxygen. The density, pressure, temperature Sun increase age.
