Abundances of 5 Ap/Bp stars of NGC 6475

The connection between age, rotation and chemical abundance of magnetic Ap stars is poorly understood. Using open clusters, we are able to study samples of stars that are both...磁Ap星（magnetic Ap stars）的年龄、自转与化学丰度之间的关联机制目前尚不完全明确。借助疏散星团，我们得以对同时兼具两类特征的恒星样本展开研究。
