论文摘要
这项研究表明，碳恒星CGCS 673是半定期（SR）变量恒星，周期为135 d，V波段中的幅度为0.18。这项研究获得的光曲线与SR分类良好相关，因为获得的光度数据显示在CGCS 673的光变化中明显的周期性，偶尔会被不规则可变性时期中断。从我们的数据和专业数据库中获得的派生周期和颜色索引表明，该星的位数属于半规则可变星类别的参数。在我们发现该恒星是可变源的发现后，CGCS 673已收到AAVSO唯一标识符，为（AAVSO UID）000-BMZ-492。
This study shows that the carbon star CGCS 673 is a semi-regular (SR) variable star with a period of 135 d and an amplitude of 0.18 magnitudes in the V-band. The light curve obtained by this study correlates well with the SR classification as the photometric data obtained shows noticeable periodicity in the light changes of CGCS 673 that is occasionally interrupted by a period of irregular variability. The derived period and colour index obtained from our data and those from professional databases indicate that the at-tributes of this star fall within the parameters of the Semi-Regular class of variable stars. Following our notification of the discovery that this star is a variable source, CGCS 673 has received the AAVSO Unique Identifier as (AAVSO UID) 000-BMZ-492.
