The chemical compositions of solar twins in the open cluster M67

Liu, Fan; Asplund, Martin; Yong, David; Melendez, Jorge; Ramirez, I; Karakas, Amanda; Carlos, Marília; Marino, Anna


Stars in open clusters are expected to share an identical abundance pattern. Establishing the level of chemical homogeneity in a given open cluster deserves further study as it is the basis of the concept of chemical tagging to unravel the history of the Milky Way. M67 is particularly interesting given its solar metallicity and age as well as being a dense cluster environment. We conducted a strictly line-by-line differential chemical abundance analysis of two solar twins in M67: M67-1194 and...[Show more]
