The online Catalogue of Galactic High-Mass X-ray Binaries, 5th Edition

This website offers a quick way to browse the catalogue of HMXBs as published in [ref]. We also regularly update the data available and publish downloadable versions based on new information available on the current binaires / new discoveries.

Column description

Main ID

The most commonly used and/or historical identifier of the source.

[Hidden] Simbad IDs

Complete list of all identifiers available for the source in the Simbad database.

Spectral type

Spectral type of the companion star in the binary.

Class

Subtype of HMXB according to the spectral type. sg: supergiant HMXB Be: Be HMXB SFXT: Super Fast X-ray Transient sgB[e]: supergiant with forbidden emission lines WR: Wolf-Rayet

Right ascension, Declination, Error radius

Sky coordinates from the most accurate counterpart we found. Right ascension and Declination are given in degrees. The 90\% positional error radius is given in milli-arcsecond (mas).

Distance

Geometric distance to the source as published in Bailer-Jones (2021). Note: this is only available to HMXBs with a Gaia counterpart.

Mx, Mo

Masses of the compact object (Mx) and of the companion star (Mo), given in Solar Mass.

Period

Orbital period of the binary system, given in days.

Super orbital period

Super orbital period detected in the binary, given in days.

Eccentricity

Eccentricity of the orbital solution for the binary.

Spin period

Spin (or pulse) period detected in the binary, given in seconds.

Radial velocity

Systemic radial velocity of the binary (unaffected by orbital motion), given in km/s.

Variable ?

Flag for variability taking into account results from the INTEGRAL, 4XMM DR11, Chandra and Swift 2SXPS catalogues.
