We gratefully acknowledge NASA’s support for construction, operation, and science analysis for the GALEX mission, developed in cooperation with the Centre National d’Etudes Spatiales of France and the Korean Ministry of Science and Technology. We thank C. Popescu and R. Tuffs for their comments. S. B. thanks the CNES for its financial support. | |
| dc.description.abstract | We use the far-UV (FUV) and near-UV images of M83 obtained by the Galaxy Evolution Explorer (GALEX) to compute the radial profile of the UV spectral slope in the star-forming disk. We briefly present a model of its chemical evolution, which allows us to obtain realistic intrinsic properties of the stellar populations. Using corollary data, we also compute the profiles of Hα/Hβ and total-IR/FUV ratios. Both the data and model are used to estimate and compare the extinction gradients at the FUV wavelength obtained from these various indicators. We discuss the implications for the determination of the star formation rate. | |
