Descripción
The Milky Way satellites offer the possibility of studying their star formation histories in great detail. Color-magnitude diagrams (CMDs) reaching the old main-sequence turnoffs, allow a careful modelling of their stellar populations using synthetic CMDs, and spectroscopy of the brightest stars, provides a direct measurement of their metallicity. Here I present new wide field, old main sequence turnoff photometry of the LMC and Fornax, and briefly discuss preliminary results of a CaII triplet spectroscopy study of metallicities of individual stars in Fornax.
