Physics

Scientific paper

We propose to investigate two key dust tracers (silicate dust and very small grains) across the closest starburst known IC10. By comparing the spatial distribution of silicate dust in the diffuse ISM with the visual extinction map, we will investigate the possible relation between silicate dust and large carbonaceous grains. Our observations will enable us to probe the silicate dust properties as a function of the local physical conditions, notably the hardness of the radiation field. In a second part, we intend to study the nature and evolution of PAHs and VSGs toward the many giant molecular clouds (GMCs) within IC10. We propose to address the formation process of very small grains within GMCs.
