... The history of star formation was successfully analyzed for the first time based on the spectra of the stellar population of dwarf galaxies of low surface brightness outside the Local Group. We have investigated the stellar population of two dwarf spheroidal galaxies KDG61 and KDG64 in the central part of a close group of galaxies M81. ... These galaxies are dominated by the old stellar population (12-14 billion years) of low metallicity ([Fe/H] ~ -1.5). ... KDG61 . ... KDG64 ...
