英文摘要 | We present [O/Fe] and other alpha-elements/Fe ratios in a sample of 24 mildly metal-poor stars The sample stars are thought to be brighter than 9.0 magnitude and have available uvby photometric data. Also, based on the typical LTE abundance analysis, we find that [Si/Fe] and [Ca/Fe] are correlated with each other. Combining the kinematic data and the metallicity, we can classify the sample stars into three groups. An abundance analysis :shows some evidence that these groups are chemically discrete from each other. Further, the general trend of a decreasing overabundance of the a elements with increasing metallicity has been confirmed. |
