We present a detailed study of the stellar kinematics in the barred galaxyNGC 5728 based on I-band photometry and long-slit spectroscopic observations inthe region of the near-IR Ca II triplet. The analysis of the stellarline-of-sight velocity distribution (LOSVD) has revealed, in the centralregions of the bar, the presence of a cold (v/sigma~2.5) prograde $S$-shapedvelocity component that coexists in the central 4 kpc with a fainter and hotter(v/sigma~0.5) counterrotating component. Beyond 4 kpc from the nucleus theLOSVD shows the stellar bar kinematics. The comparison of the radial surfacebrightness profile of the velocity components with that obtained from an I-bandimage shows that the counterrotating core follows a r^(1/4) profile, while theS-shaped component does not follows the flat bar surface brightness profile.Several possible scenarios accounting for such kinematic signatures found inthe center of the bar in NGC 5728 are discussed.Comment: 11 pages, 8 figures, accepted for publication in Astrophysical  Journa
