The population in the background of open clusters: tracer of the Norma-Cygnus arm.

PANDEY A.K., SHARMA S. and OGURA K.

Abstract (from CDS):

We present colour-magnitude diagrams of open clusters, located in the range 112° < l < 252°, manifesting stellar populations in the background of clusters. Some of the populations are found to be located beyond the Perseus arm and may be the part of the Norma-Cygnus (outer) arm. The outer arm seems to be continued from l ∼ 120° to ∼235°. The background populations follow the downward warp of the Galactic plane around l ∼ 240°.
