Título/Title: Chemical and spectrophotometrical evolution of spiral and irregular galaxies


The elemental abundances and their variations from galaxy to galaxy or within them provide important information related on the evolution of galaxies, mainly the star formation and the infall of gas histories in spiral disks and irregular galaxies. The basic ideas and main processes which have a role in the chemical evolution of galaxies will be described. Then I will explain the multiphase chemical evolution model from Molla & Diaz (2005) and I will show the evolutionary histories of a set of theoretical galaxies obtained with a grid of realistic models able to reproduce the data of our local universe.
