Scientific paper

Morphological and kinematical observations of NGC 4589 are presented. The galaxy shows a dust disk rapidly rotating about the major axis. Modeling of the dust disk leads to a mass of 4 x 10 to the 7th solar masses of interstellar material. The stellar velocity field was mapped along four position angles. While rotation about minor and major axes is observed, the axis of zero rotation is positioned about 45 degrees in between. The observations indicate that NGC 4589 is a merger remnant.
