Project VeSElkA: HD stars atomic-line analysis

A portion of main-sequence stars, called chemically peculiar (CP) stars, show important abundance anomalies mainly due to atomic diffusion of the species within these stars....部分主序星被归类为化学特殊星（chemically peculiar (CP) stars），这类天体呈现出显著的丰度异常特征，其成因主要源于恒星内部各化学元素的原子扩散作用。
