Galaxies, Barred Galaxies: Morphology, Triaxial Bulge

Scientific paper

We have examined bulge morphology of 104 bright barred galaxies, using V-band surface photometry based on the Kiso-Schmidt plates. By measuring the bulge ellipticity and bulge-disk misalignment, we have classified bulges into four morphological types: sphere, oblate spheroid, triaxial ellipsoid, and pseudo triaxial ellipsoid. About half of the observed galaxies are found to have triaxial bulges with mean ellipticity of 0.24. They are distributed uniformly along the Hubble sequence.
