Identification of 12 Nearby Stars with Mid-Infrared Excess: Potential Debris Disk Candidates from Gaia-AllWISE

We report the identification of 12 nearby stars exhibiting significant mid-infrared (MIR) excess, suggesting the presence of circumstellar debris disks. By cross-matching a volume-limited parent sample of 2,000 sources from Gaia DR3 with the AllWISE Source Catalog, we successfully recovered infrared photometry for 1,984 stars (99.2% match rate). From this high-fidelity merged dataset, we isolated 12 candidates that exhibit extreme deviations from expected stellar photospheric emission. These candidates are confirmed Main Sequence stars with high-significance W4 (∼22 µm) excess. These targets represent prime candidates for investigating the architecture of extra-solar asteroid belts and the evolutionary history of planetary systems in the solar neighborhood.
