Age distribution of lmc clusters from their integrated ubv colors : history of star formation
Girardi, Leo Alberto; Chiosi, Cesare; Bertelli, Gianpaolo; Bressan, Alessandro (1995) [Artigo de periódico]In this paper we revise the relationship between ages and metallicities of LMC star clusters and their integrated UBV colors. The study stands on the catalog of UBV colors of the Large Magellanic Cloud (LMC) clusters by ... -
Mass loss from red giant stars in M67 : is there any evidence for a metallicity dependence?
Carraro, Clóvis Carlos; Girardi, Leo Alberto; Bressan, Alessandro; Chiosi, Cesare (1996) [Artigo de periódico]Recent claims in the literature, that the rate of mass loss from red giant branch (RGB) stars in old, open clusters like M 67 and NGC 6791, increases with the metallicity above the value holding for Globular Clusters and ...
