论文摘要
在坐标RA（J2000）22：49：05：49和DEC（J2000）+57：52：41：6的红色巨型MACOMP_V1（J2000）22：49：05：49和DEC（J2000）+57：52：41：6是一个分类为SRS的半牙变量星，AAVSO VSX数据库中的数字2225960。使用傅立叶变换，评估了周期p = 24.751（0.062）d，并在ASAS-SN和ZTF调查的支持下，进行了明确定义的光曲线。分析导致MACOMP_V1的基本物理参数，例如质量M = 4.97（0.38）m（Sun）和Radius r = 40.5（6.7）R（Sun），其值一致，表明了半牙的红色巨人的特征。此外，估计了基于Schoenberg-Chandraskehar极限的Gaia目录和恒星进化的有效温度TEFF = 4500（135）K。
The red giant MaCoMP_V1 in Cepheus at coordinates RA (J2000) 22:49:05:49 and DEC (J2000) +57:52:41:6 is a semiregular variable star classified as SRS, number 2225960 in the AAVSO VSX database. Using the Fourier transform, the period P = 24.751(0.062)d was evaluated and, with the support of the ASAS-SN and ZTF surveys, a well-defined light curve was made. The analysis resulted in the fundamental physical parameters of MaCoMP_V1, such as the mass M = 4.97(0.38)M(Sun) and radius R = 40.5(6.7)R(Sun), with consistent values suggesting the characteristics of a semiregular red giant. In addition, the effective temperature Teff = 4500(135)K from the Gaia catalog and the stellar evolution based on the Schoenberg-Chandraskehar limit was estimated.
