Fabry-Pérot Hα Observations of the Barred Spiral NGC 3367

We report the gross properties of the velocity field of the barred spiral galaxy NGC 3367. We obtained the following values: the inclination with respect to the plane of the sky, i = 30; the position angle (P.A.) of the receding semimajor axis, P.A. = 51°; and the systemic velocity, Vsys = 3032 km s-1. Large velocity dispersions are observed of up to 120 km s-1 in the nuclear region and of up to 70 km s-1 near the eastern bright sources just beyond the edge of the stellar bar, where three spiral arms seem to start, and in the western bright sources at about 10 kpc. Deviations from normal circular velocities are observed from the whole disk but mainly from the semicircle formed by the string of southwestern Hα sources. An estimate of the dynamical mass is Mdyn = 2 × 1011 M⊙.
