Descripción
We report the case of the early-type disk galaxy NGC 4672 as a new
example of a galaxy characterized by the orthogonal geometrical
decoupling between bulge and disk. The morphological features of this
galaxy are discussed as well as the velocity curves and velocity
dispersion profiles of stars and ionized gas along both its major and
minor axis. We conclude that NGC 4672 has structural (i.e. a bulge
elongated perpendicularly to the disk) and kinematical (i.e. a stellar
core rotating perpendicularly to the disk) properties similar to those
of the Sa NGC 4698. The presence of the isolated core suggests that the
disk component is the end result of the acquisition of external material
in polar orbits around a pre-existing oblate spheroid as in the case of
the ring component of AM 2020-504, the prototype of polar ring
ellipticals. Based on observations carried out at ESO, La Silla (Chile).
