Information on Service 'Galactic X-ray Pulsars'

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.

Overview

You can access this service using:

scs.xml -- a standard SCS interface as defined by the IVOA to access catalog-type data; SCS clients use https://dachs.fai.kz/pulsars/q/scs/scs.xml? to access the service
form -- an interface for web browsers through an HTML form

This service is published as follows:

Within the set(s) ivo_managed with the renderer dali
Within the set(s) local,ivo_managed with the renderer form
Within the set(s) ivo_managed with the renderer scs.xml

local means it is listed on our front page, ivo_managed means it has a record in the VO registry.
