The R1R2' outer ring revealed by young open cluster data
arXiv:1602.01708 · doi:10.1515/astro-2017-0111
Abstract
The distribution of young open clusters in the Galactic plane suggests the existence of the outer ring R1R2' in the Galaxy. The solar position angle theta_b providing the best agreement between the observed and model distribution is theta_b=35 +\- 10 degrees. We compared the theta_b values derived from three different catalogues of open cluster and they appear to be consistent within the errors.
