A Chemical Evolution of Draco Dwarf Galaxy: Monolithic or Merger Scenario?
Main Astronomical Observatory NASU, Ak.Zabolotnoho St. 27, Kyiv 03680, Ukraine
A chemical evolution of the Local Group dwarf galaxy Draco is considered. The stellar metallicity distribution function of Draco was calculated in the framework of both the monolithic and the merger scenario. The observed metallicity distribution isn’t reproduced quite well by monolithic collaps for this galaxy. The use of a merger of several fragments allows to obtain a better resemblance between modelled and observed stellar metallicity distributions.
