Bar Presence in Local Galaxies: Dependence on Morphology in Field Galaxies

Abstract We analyzed the fractions of barred galaxies in the local Universe using a volume-limited sample of galaxies from the Sloan Digital Sky Survey Data Release 3. We examined 116 field galaxies with redshifts between 0.0207 and 0.030, using r and z -band images. Overall, the bar fraction was 26% in the r -band and 19% in the z -band. For distinct morphological groups, barred spiral galaxies had fractions of 33% in the r -band and 22% in the z -band, while barred lenticular galaxies had 25% in the r -band and 12% in the z -band. We observed that the bar fraction in spiral galaxies increases for stellar masses log ( M * / M ⊙ ) > 10.5 and for galaxies with red colors ( u − r ) > 2.0. Additionally, most barred galaxies have a bulge-to-total ratio B / T ≤ 0.2. Our results indicate that the bar fraction is more dependent on internal morphology than on the galaxy environment.
