| Abstract: |
We present the project Local Cosmology from Isolated Dwarfs (LCID), aimed at deriving detailed star-formation histories for a sample of Local Group isolated dwarf galaxies. To accomplish this goal we have collected, using the ACS on board the HST, color-magnitude diagrams reaching the oldest main sequence turnoff (V ≃ 29) with good photometric accuracy. Some preliminary results from the color-magnitude diagrams, and the populations of variable stars are shown and briefly discussed. |
