A new interpretation of the galactic structure from H II regions
Published online by Cambridge University Press: 14 August 2015
Abstract
From 6000 optical radial velocities of H II regions a new spiral structure (4 arms of pitch angle 20°) is found. The radial velocities of the observed H II regions are the same with the velocities of the H I regions. The kinematics of H II regions is similar to that of Cepheids and B stars.
