摘要

本文介绍了iXon Ultra 888 EMCCD相机的测试结果，以确定恒星短曝光光度测量的工作参数。通过测试，选择了电子倍增电荷的时间不稳定性对光曲线影响不大的相机模式。此外，本文还介绍了俄罗斯科学院特殊天体物理天文台蔡司-1000望远镜对日蚀变星ZTF J 0038+2030的光度测量结果。我们已经说明了1-s曝光用于研究变星的优点和缺点。

Photometric Stability of an EMCCD Camera at 1-s Exposures

We present the results of testing an iXon Ultra 888 EMCCD camera to determine the operating parameters for short-exposure photometry of stars. As a result of the testing, those camera modes were selected in which the temporal instability of the electron multiplication charge does not significantly affect the light curves. In addition, the photometry of the eclipsing variable star ZTF J 0038+2030, obtained with the Zeiss-1000 telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences, is presented. We have shown the advantages and disadvantages of 1-s exposures for studying variable stars.
