A Consensus-driven and Physically Validated Catalog of Metallic-line A-star Candidates from LAMOST DR12 Based on Physics-constrained Generative Augmentation with a High-confidence Core of 18,408 Objects

We present a consensus-driven and physically validated catalog of 36,226 metallic-line A-star (Am) candidates from LAMOST DR12, constructed by a multimethod framework with physics-constrained generative augmentation, and containing a high-confidence core of 18,408 objects. A high-purity benchmark of...
