The feasibility of detecting candidate slow-rotating magnetic Ap stars with periods from a few tens of days to several hundred years is considered. The question of the fraction of objects of this kind among all Ap stars is important from the standpoint of understanding the origin and evolution of magnetic stars. The search for such objects can be based on analysis of their photometric variability using observations from the TESS space mission. For this purpose, it is first planned to examine all the objects from the corresponding catalogs. It is shown how the proposed method may be used for the example of the slowrotating Ap star HD 50169, with a detailed analysis of its variability and for which observations from the TESS mission are already available.

缓慢旋转的 Ap 星，苔丝太空任务对其进行观测的前景

考虑了探测周期从几十天到几百年的候选慢旋转磁Ap星的可行性。从理解磁星的起源和演化的角度来看，所有Ap星中此类物体的比例问题很重要。对此类物体的搜索可以基于使用来自 TESS 太空任务的观测结果对它们的光度变化进行分析。为此，首先计划检查相应目录中的所有对象。展示了所提出的方法如何用于慢速旋转的 Ap 星 HD 50169 的例子，详细分析了它的可变性，并且 TESS 任务的观测已经可用。
