论文摘要
我们介绍了在2019年和2020年在Lickobservatory进行的镍1 m望远镜观测的球状簇M15中的74个RR Lyrae星的时期，幅度和类型的测量值。此外，我们确定了五个II型头孢菌变量恒星，我们为此报告了三个新的时期确定，另外34颗恒星具有不确定的分类和周期。我们基于新的自适应自由式拟合技术，讨论了新的Python软件包，周期性确定和识别管道套件（PIPS）的数据的开发和后续应用，以清晰的治疗不确定性，以检测可变星的周期。
We present measurements of the periods, amplitudes, and types of 74 RR Lyrae stars in the globular cluster M15 derived from Nickel 1 m telescope observations conducted at LickObservatory in 2019 and 2020. Of these RR Lyrae stars, two were previously reported but without a determination of the period. In addition, we identify five Type II Cepheid variable stars for which we report three novel period determinations, and a further 34 stars with uncertain classifications and periods. We discuss the development and subsequent application to our data of a new Python package, Period-determination and Identification Pipeline Suite(PIPS), based on a new adaptive free-form fitting technique to detect the periods of variable stars with a clear treatment of uncertainties.
