Information on Service 'Galactic X-ray Pulsars'

[Use this service from your browser]

Further access options are discussed below

This catalog contains data on the Galactic population of 82 confirmed X-ray pulsars in high-mass X-ray binary (HMXB) systems, classified into 18 persistent and 64 transient sources. Key parameters include spin periods, spin evolution (local and global trends), orbital periods, X-ray luminosities, magnetic fields, distances, and detailed companion star characteristics. The data have been compiled through cross-matching with recent HMXB catalogs and databases such as Fortin et al. (2023), Neumann et al. (2023), and Krivonos et al. (2022), supplemented with literature and SIMBAD database analysis. The catalog aims to support studies on stellar evolution, accretion processes, and binary dynamics.

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
