Catalog of High-Mass X-Ray Binaries in the Galaxy (Dynamic Version)

They search for as many hard X-ray, soft X-ray, optical and infrared counterparts to the HMXBs as we can in well-known catalogs and compile their coordinates. Each HMXB is subject to a meticulous search in the literature to find relevant measurements and their original reference. The authors provide a catalog of HMXBs in the Galaxy with their best known coordinates, companion star spectral type, systemic radial velocities, component masses, orbital period, eccentricity and spin period when available.

This catalog also provides the coordinates and identifiers for each counterpart found from hard X-rays to near-infrared, including counterparts from the recent Gaia DR3 catalog. This catalog was created from data-mining the published literature. It takes into account information available through 2022.

Values for binary parameters are joined with a reference in which the value was derived. Position data for which the authors have manually found a counterpart also have a specific reference; if not, then the data comes directly from the corresponding catalog. This database table was first created by the HEASARC in October 2023, based on the 2023-09 version of this catalog, found from the <a href="binary-revolution.github.io/HMXBwebcat/">Binary rEvolution website</a>.

It is automatically updated in the HEASARC database within a few days of a new version being released on that website. This is a service provided by NASA HEASARC .
