The derivation of precise stellar ages is considered the current major challenge to reconstruct the chronological chain of events that shaped the Milky Way (MW). Despite much effort and hope have been deposited in upcoming asteroseismology works, we have shown that CMD-fitting already offers an alternative to age determinations via the derivation

Simultaneous multicolor photometry is an important source of observational data providing priceless information on different physical processes that cannot be obtained in other ways. It can provide modal identification for classical pulsators, information about the stellar spots structure, or clues for identifying false positives in exoplanetary

Given their low surface brightness, it is hard to determine high-quality spectra of dwarf galaxies outside the Local Group, where it is not possible to study the individual stars. Although several studies exist that use absorption line lengths to study the stellar populations of dwarf galaxies, studies of the Star Formation Histories in these
