In these "X-ray binary
" systems, the black hole - or neutron star - pulls gas from its companion star, and that gas falls onto the accretion disk around the black hole.
Using archival data from the Chandra X-ray Observatory telescope, a Columbia University-led team of astrophysicists has discovered hundreds of inactive low-mass x-ray binary
systems--binary star systems in which one of the components is a black hole--within a parsec (approximately 3.3 light years) of Sgr A*, in the centre of the Milky Way Galaxy.
Many astronomical X-ray sources are Soft X-ray Transients (SXT) which are bursts of X-ray binary
systems with accreting neutron stars or black hole.
(2016) Application of the Ghosh & Lamb relation to the spin-up/down behavior in the X-ray binary
pulsar 4U 1626-67.
The system is called an X-ray binary
because it emits X-rays as material from the companion star spirals onto the much denser neutron star and is heated to very high temperatures.
In what's called a low-mass X-ray binary
, a neutron star is spun up to a millisecond rotation period by material siphoned from its regular stellar companion.
5 ( ANI ): X-rays streaming towards Earth from the region near a neutron star that is cannibalizing its companion star are the youngest "X-ray binary
" yet known, according to scientists.
Figure 1 shows a sketch of an X-ray binary
system as it would be seen by a nearby observer.
That energy is visible as a bright spot called an X-ray binary
A "symbiotic X-ray binary
" 6 a star system made up of a red giant star and a neutron star 6 is extremely rare.
