TL;DR
This paper presents the first all-sky mid-infrared variable star catalog from WISE data, discovering over 50,000 variables including many new types, and establishing a classification method based on light curves.
Contribution
It introduces a comprehensive mid-infrared variable star catalog with a novel classification approach and a large number of newly identified variables, enhancing Galactic and stellar evolution studies.
Findings
Discovered 50,282 periodic variables, 69% of which are new.
Developed a classification method using mid-infrared light curves.
Achieved high agreement with existing catalogs in classification accuracy.
Abstract
We have compiled the first all-sky mid-infrared variable-star catalog based on Wide-field Infrared Survey Explorer (WISE) five-year survey data. Requiring more than 100 detections for a given object, 50,282 carefully and robustly selected periodic variables are discovered, of which 34,769 (69%) are new. Most are located in the Galactic plane and near the equatorial poles. A method to classify variables based on their mid-infrared light curves is established using known variable types in the General Catalog of Variable Stars. Careful classification of the new variables results in a tally of 21,427 new EW-type eclipsing binaries, 5654 EA-type eclipsing binaries, 1312 Cepheids, and 1231 RR Lyraes. By comparison with known variables available in the literature, we estimate that the misclassification rate is 5% and 10% for short- and long-period variables, respectively. A detailed comparison…
