Velocities and proper motions of Galactic Cepheids
Listed in IVOA Registry (Virtual Observatory)
The kinematics and distribution of classical Cepheids within ~3 kpc from the Sun suggest the existence of the outer ring R1R2' in the Galaxy.
Description
The optimum value of the solar position angle with respect to the major axis of the bar, theta_b, providing the best agreement between the distribution of Cepheids and model particles is theta_b_=37+/-13{deg}. The kinematical features obtained for Cepheids with negative Galactocentric radial velocity V_R_ are consistent with the solar location near the descending segment of the outer ring R2.
The sharp rise of extinction toward of the Galactic center can be explained by the presence of the outer ring R1 near the Sun.
