Photometrical Mapping in Barred Galaxies: Analysis of the Different Components

  • D. Bettoni (a1), G. Fasano (a1) and G. Galletta (a2)

Abstract

We analyzed a sample of SBO galaxies in order to disentangle the structure of the bar and of the other components inside the galaxies. The disk and the bulge components, modeled by using the luminosity and geometrical profiles, have been subtracted from each galaxy image in order to obtain the image of the bar. This allowed us to analyze in detail the bar structure, in particular its shape and its luminosity profile. Both uniform and saddle-shaped bars have been detected.
