Abstract : According to Lambda cold dark matter model, galaxies grow in mass through hierarchical assembly of smaller systems. These interactions create tidal features (stellar and gaseous streams), trigger star formation activity and eventually build up the outskirts of their host galaxy. Theoretically this kind of assembly process is scale-free. Though the processes regulating star formation and the interstellar medium in pairs of interacting massive galaxies in the local universe have been studied extensively, similar studies to understand the impact of interactions between low mass, dwarf galaxies (stellar mass $\lsim$ 5 $\times$ 10$^{9}$ solar mass) are very limited. The effect of interactions on the scales of dwarf galaxies can be best studied in low-density environments where the effects of nearby massive galaxies are minimal. In this context, to understand galaxy interactions and associated star formation on smaller scales, we study and compare the star formation properties of nearby interacting and isolated dwarf galaxies in low-density environments using UV data. Results from this study will be presented.
