AbstractThe HII regions in the Large Magellanic Cloud (LMC) provide an ideal laboratory to study various processes of dust formation and evolution. The LMC has been targeted by many space-based telescopes, including NASA's Spitzer Space Telescope and more recently, JAXA's AKARI satellite owing to its known distance and nearly face-on orientation with respect to the Milky Way (MW). The highest LMC reddening occurs in the 30 Doradus HII region where the color excess E(sub B-V) reaches a maximum of 0.29. We have done correlation studies in this region between far-ultraviolet (FUV) observations made by the FUSE telescope and infrared (IR) observations made by AKARI in the recent past. In this work, we have attempted to model the FUV scattering by 20 hot stars in the 30 Doradus region within a 1 deg radius. We have chosen an ideal dust distribution facilitating us to study the emission properties around the centre of the nebula. We will also model the IR emission later to conclusively prove the dust properties in the region.
