Dwarf irregular galaxies can trace their origins to two formation scenarios (i) they are formed due to the collapse of a primordial gas cloud or (ii) by the condensation of gas in the tidal tails of interacting galaxies. The difference between these two scenarios can be determined by the presence or absence of dark matter in galaxies. Various studies have shown that some dwarf galaxies are rich in dark matter while others are not, hence exhibiting a range in dark matter content. Tidal dwarf galaxies should contain less dark matter than normal dwarf irregular galaxies. The dark matter content could have consequences on the star formation properties as well. In an attempt to establish the dark matter content, and consequently its origins, we will be studying the dwarf galaxy DDO 210. Here we present some preliminary results.
