Abstract
We have derived a robust star formation history (SFR) for NGC 6822, an irregular galaxy of the Local Group, based on observations and photometric evolution models. That SFR can be used for different applications related to NGC 6822. Our photometric model computed with GALAXEV code of Bruzual and Charlot (2003) and based on the adopted SFR, the IMF by Kroupa, Tout & Gilmore (1993, KTG), and the metallicity evolution, Z(t) obtained by the chemical evolution model predicts absolute magnitudes and colors that agree with the observed ones at the one σ level.
