  Abstract:
Amongst the dwarf galaxies in the Local Group, the isolated irregular one, IC 10 is one of the most interesting galaxies, with strong star forming activity and the highest density of Wolf-Rayet stars. Undergoing a starburst phase, having numerous HII regions and being bright in all wavebands, makes it an exquisite galaxy to study the internal and external processes that continue to affect dwarf galaxies 14 Gyr since the Big Bang. In this study, we present a new deep and precise optical monitoring survey of IC 10 using the Isaac Newton Telescope (INT) with the wide field camera (WFC). We performed observations at nine epochs spaced between three to four months apart between 2015 and 2017. We identified Long Period Variable stars (LPVs), Asymptotic Giant Branch stars (AGBs) and Red Super Giant stars (RSGs) to determine the star formation history and chemical evolution of IC 10.
