NGC 6709 cool stars rotation periods

Open clusters serve as a useful tool for calibrating models of the relationship between mass, rotation, and age for stars with an outer convection zone due to the homogeneity of...

疏散星团（Open clusters）可作为校准具有外对流区（outer convection zone）恒星的质量、自转与年龄之间关系模型的有效工具，这源于其……的均一性。
