AAVSO Variable Star Index (VSX)
Part of the Astronomy Datasets collection on Hugging Face.
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.
Dataset description
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.
