Abstract

We report the preliminary results of our numerical simulations of the Galactic chemical evolution of stable isotopes from ¹H to ⁶⁹Ga. The Galaxy was formed in two episodes of accretion: an early rapid accretionary episode, followed by a declining accretion rate. Successive generations of 1-100 M_⊙ stars were numerically simulated to evolve in a realist manner the entire evolution of the Galaxy since the initiation of its formation. This is perhaps the first attempt to numerically simulate the Galactic chemical evolution without solving the classical set of integro-differential equations. We could successfully simulate the history of star formation rate, the white-dwarf, neutron star and black hole generation rate of the Galaxy in the solar neighborhood. Further, we could explain the stable isotopic abundance of ¹H to ⁶⁹Ga at the time of formation of the solar system around 4.5 billion years ago.
