| 单词 | x-ray binary star |
| 释义 | x-ray binary starA binary star system that produces a significant amount of x-ray radiation. When one of the components of a binary system is an extremely dense body such as a white dwarf or a neutron star, its enormous gravitational attraction can pull material from the other star into its own orbit, causing the accelerated matter to release high-energy photons in the x-ray spectrum.
