摘要：

We present preliminary results from an ongoing study of the bulges of SO galaxies. We show that in a subsample of 14 barred SO galaxies, fully half the photometrically defined bulges show kinematic signatures of pseudobulges - that is, their kinematics are dominated by rotation. In four of these galaxies, we identify at least two subcomponents in the photometric bulge region: flatter, disk or bar components, assocated with disklike kinematics, and rounder "inner bulges," which appear to be hotter systems more like classical bulges.
