VarWISE catalogs infrared-variable objects discovered within the NEOWISE single-exposure data. VarWISE employs unique methodologies, including the spatial clustering of apparitions and the adoption of novel machine learning-based variable detection (VARnet) and classification (XGBoost) to identify and characterize significant variability. The catalog includes a prediction of variable object type and best-fit period values for each object, if its variations are cyclical, along with other calculated parameters to characterize the nature of the variability. The VarWISE Pure Catalog, containing only variables of highest confidence, has 457,080 objects, 49.81% of which are new discoveries; the VarWISE Extended Catalog, containing all sources, has 1,918,082 objects, 82.02% of which are new. https://irsa.ipac.caltech.edu/data/WISE/VarWISE/overview.html Survey Research served-by IRSA TAP service 2 https://irsa.ipac.caltech.edu/SCS?table=varwisepure& 180 457080 false 45.20391 0.9113 0.01 2 To access this resource via TAP, issue ADQL queries on the table named varwisepure. https://irsa.ipac.caltech.edu/TAP 2 https://irsa.ipac.caltech.edu/cgi-bin/Gator/nph-dd?catalog=varwisepure Infrared varwise WISE/NEOWISE Enhanced and Contributed Products varwisepureVarWISE Pure Catalog
