X-ray binary
(XRB, binary X-ray system)
(binary star emitting X-rays)
An X-ray binary (XRB) or binary X-ray system is a binary star
that produces X-rays. They are ascribed to the inclusion of
a neutron star or stellar-mass black hole that is accreting
from its companion, producing X-rays through shock.
They are often classified by the mass of the compact object's
companion:
- low-mass X-ray binaries (LMXB)
- intermediate-mass X-ray binaries (IMXB)
- high-mass X-ray binaries (HMXB or massive X-ray binaries, MXRB)
With a strong magnetic field, the binary might produce periodic
X-ray pulses, i.e., an X-ray pulsar.
Otherwise, it may produce occasional
burst-transients, (X-ray bursts),
i.e., an X-ray nova aka X-ray burster.
The bursts may be due to varying levels of accretion.
A Be X-ray binary (BeXRB) is a such a binary that includes a Be star.
X-ray binaries are one of the methods of detecting stellar-mass
black holes: over a hundred Milky Way X-ray binaries suggests
a black-hole companion.
