Abstract
Investigation of gaseous and stellar kinematics and of broadband VRI and narrowband Hα and [N II] λ6583 images is performed for the central part of the regular spiral galaxy NGC 2841 (R < 4 kpc). We found emission-line splitting at R < 20'' and a three-component line-of-sight velocity distribution (LOSVD) for the stars in the radial range 6'' to 100''. Morphological analysis reveals strong narrow shock fronts close to the major axis in the radial range from 30'' to 50'', a turn of 5° in the isophote major axis, and a strongly negative Fourier coefficient a4 (boxy isophotes) in the radial range from 15'' to 33''. In principle, all these features may be explained in the context of a triaxial bulge hypothesis.Keywords
