Abstract
We map and study the dynamics of the Milky Way’s spiral arms in our vicinity, using the birth place of open clusters. Since these objects are located in the galactic plane and are born primarily in the arms, they are an excellent tool for analyzing the dynamics of the spiral structure. Using their birth place, we find evidence for multiple spiral patterns with different speeds. The Carina arm appears now to be a superposition of both. The results are important for proper modeling of cosmic ray diffusion in our galactic vicinity.
