Fitted UBV magnitude for MS stars

We fit the colour-magnitude diagrams of stars between the zero-age main-sequence and terminal-age main sequence in young clusters and associations. The ages we derive are a...我们针对年轻星团与星协内处于零年龄主序星（zero-age main-sequence）与终端年龄主序星（terminal-age main sequence）之间的恒星，对其色星等图（colour-magnitude diagrams）开展了拟合。我们推导得到的年龄为……
