AAVSO变星索引（VSX）是最全面的变星目录，包含10,300,820个条目，涵盖变星分类、测光属性、周期和光谱类型。VSX由美国变星观测者协会维护，是变星研究的标准参考。该数据集汇总了来自全球数百个巡天和目录的变星数据，包括OGLE、ASAS-SN、ZTF、Gaia和AAVSO观测者提交的数据。每个条目代表一个独特的已确认或疑似变星，包含其变光类型、亮度范围、周期（如果已知）、历元和光谱分类。在10,300,820个条目中，有4,830,314个具有测量周期，10,292,210个具有变光分类。

The AAVSO Variable Star Index (VSX) is the most comprehensive catalog of variable stars, containing 10,300,820 entries with variable star classifications, photometric properties, periods, and spectral types. VSX is maintained by the American Association of Variable Star Observers and is the standard reference for variable star research. VSX aggregates variable star data from hundreds of surveys and catalogs worldwide including OGLE, ASAS-SN, ZTF, Gaia, and AAVSO observer submissions. Each entry represents a unique variable or suspected variable star with its variability type, brightness range, period (if known), epoch, and spectral classification. Of the 10,300,820 entries, 4,830,314 have a measured period and 10,292,210 have a variability classification.
