Globular cluster NGC 6397 variable stars

We present a new time-series VI CCD photometry of the globular cluster NGC 6397, from which we obtained and analysed the light curves of 35 variables carefully identified in the...本研究针对球状星团NGC 6397获取了全新的VI波段时序电荷耦合器件（Charge-Coupled Device，CCD）测光数据，基于该数据集，我们提取并分析了经严格甄别的35颗变星的光变曲线，并展开了相关研究（原文后续内容未完整给出）。
