时间补偿离散傅里叶变换分析PKS 1510-089红外光变周期

The Optical Variability Periodicity Analysis of PKS 1510-089 Based on Date Compensated Discrete Fourier Transform

收集了类星体PKS 1510-089红外H波段和J波段的星等值,运用DCDFT对该天体的光变周期进行分析,并与Jurkevich方法作比较.分析结果表明:运用DCDFT分析得到H波段和J波段大致存在(0.87±0.11)a的光变周期.

We have collected the data of H-band and J-band,which belongs to the PKS 1510- 089,and used the DCDFT to analysis the light period and compared with the method of Jurkev- ich. The results show that the light period is （0. 87±0. ll）a by using DCDFT,which is consistent with the result of other authors who use different methods.
