A model for the local spiral structure of the Galaxy.
Abstract
Spatial distributions of optical spiral tracers and their motions in the region of the galactic plane from 1 = 280 to 340 deg are studied. When this region is related to the entire pattern of local spiral structure a major spiral arm, Sagittarius-Carina, is revealed from 1 = 280 to 30 deg. A model of the optical spiral pattern is proposed which adequately describes the available spatial and kinematic information for the spiral tracers.
