Catalog of Galactic High-Mass X-Ray Binaries with Multi-Wavelength Counterparts

High-Mass X-ray Binaries (HMXBs) require multi-wavelength observational efforts for proper characterization. This catalog provides the best known coordinates, companion star spectral types, systemic radial velocities, component masses, orbital periods, eccentricities, and spin periods for Galactic HMXBs, compiled from literature data-mining through 2022. The NASA HEASARC first created this database table in October 2023 and maintains a dynamic version updated from the Binary rEvolution website.

Use Cases

• Modeling binary star evolution based on orbital parameters and component masses.
• Cross-matching astronomical objects across wavelengths using provided coordinates and identifiers.
• Analyzing correlations between spin period and orbital characteristics in compact objects.
• Training machine learning models for source classification using multi-wavelength counterpart data.

Strengths

• Includes data from hard X-ray to near-infrared, including Gaia DR3 counterparts, suggesting multi-wavelength coverage.
• Parameters are joined with their original literature reference, providing traceability.
• Maintained as a dynamic version that can be updated upon user request, with modifications logged.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is compiled from published literature, which may reflect publication bias or temporal gaps in coverage.
