摘要
本文利用三国联合观测获得的大量高精度光电测光数据,采用Fourier周期分析的方法,得到了δScuti型变星HD213534的多重脉动周期,认为该星存在五个以上的脉动频率.文中给出了该星的各项参量,并对其脉动模式进行了讨论,认为HD213534星是一颗以非径向脉动为主的多重周期脉动变星.
On the basis of a large amount of highprecision photoelectric photometric data obtained at three sites and by use of the method of Fourier period analysis, the multiple frequencies of HD 213534 have been obtained. Five frequencies have been definitly detected. After an analysis of the star's pulsation modes, The authors tend to think that it is a multiple frequency pulsating variable and the nonradial pulsation is the main pulsation mode.
