X-ray Binary Catalog
Credit: NASA/ESA/Hubble
Part of the Astronomy Datasets and Stellar Catalogs collections on Hugging Face.
Merged catalog of 305 X-ray binaries (116 high-mass, 189 low-mass) from NASA HEASARC, combining the HMXB catalog (Liu, van Paradijs & van den Heuvel 2006) and the LMXB catalog (Liu, van Paradijs & van den Heuvel 2007).
Dataset description
X-ray binaries are stellar systems in which a compact object (neutron star or black hole) accretes matter from a companion star, producing intense X-ray emission. They are divided into two classes based on the mass of the donor star:
High-Mass X-ray Binaries (HMXBs): The donor is a massive O or B star (typically >10 solar masses). Accretion occurs via stellar wind or Roche lobe overflow. HMXBs are found in star-forming regions and include Be/X-ray binaries (the largest subclass) and supergiant X-ray binaries.
Low-Mass X-ray Binaries (LMXBs): The donor is a low-mass star (typically <1 solar mass). Accretion proceeds through Roche lobe overflow, forming a bright accretion disk. LMXBs are concentrated toward the Galactic center and globular clusters. They include the Z and Atoll sources (classified by their X-ray color-color diagrams) and the soft X-ray transients.
X-ray binaries are natural laboratories for studying accretion physics, strong gravity, and the equation of state of ultra-dense matter. Their X-ray variability (pulsations, quasi-periodic oscillations, thermonuclear bursts) encodes information about the compact object's mass, spin, and magnetic field. Several black hole mass measurements come from dynamical studies of X-ray binary orbits.
This dataset merges the two standard reference catalogs maintained at HEASARC, providing a unified view of the known Galactic X-ray binary population with positions, X-ray fluxes, orbital periods, and companion star classifications.
