Descripción
We present preliminary results from an ongoing study of the bulges of S0
galaxies. We show that in a subsample of 14 barred S0 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.
