Star Formation Properties in Barred Galaxies (SFB). II. NGC 2903 and NGC
  7080
  Stellar bars are important for the secular evolution of disk galaxies because
they can drive gas into the galactic central regions. To investigate the star
formation properties in barred galaxies, we presented a multi-wavelength study
of two barred galaxies NGC 2903 and NGC 7080. We performed the three-component
bulge-disk-bar decomposition using the 3.6 {\mu}m images, and identified the
bulges in the two galaxies as pseudobulges. Based on the narrowband H{\alpha}
images, the star formation clumps were identified and analyzed. the clumps in
the bulge regions have the highest star formation rate surface densities in
both galaxies, while the star formation activities in the bar of NGC 2903 are
more intense than those in the bar of NGC 7080. Finally, we compared with the
scenario of bar-driven secular evolution in previous studies, and discussed the
possible evolutionary stages of the two galaxies.
