Bright, Multiple & Variable Stars Catalog
Cross-walk of nearby dwarfs, first-magnitude navigation beacons, visual multiple systems, and prototype variable stars.
Compiler & Survey Epoch: ESA Hipparcos & Gaia DR3, USNO WDS, and AAVSO VSX / GCVS
Catalog Scope & Cross-Identification Notes
Stellar astronomy bridges the immediate solar neighborhood (Proxima Centauri at 1.30 pc, Sirius at 2.64 pc, Tau Ceti at 3.65 pc) and luminous supergiant and binary systems distributed across the local Orion spur.
This catalog unifies FastAstro's single, multiple, and variable star profiles across Bayer Greek letters, Henry Draper (HD) spectroscopic numbers, Hipparcos (HIP) and Gaia DR3 astrometric IDs, Washington Double Star (WDS) pairs, and GCVS variable classifications.
