A low mass X-ray binary (LMXB) is a celestial system in which a relatively normal star is being eaten alive by a nearby stellar corpse, either a neutron star or a black hole.

低质量X射线双星(LMXB)是一颗相对正常的恒星和邻近的正在对其进行蚕食的恒星“遗体”构成的天体系统，“遗体”是中子星或黑洞。

Additionally, if the X-ray source is in a binary system, the X-rays will be periodically cut off as the source eclipsed by the companion star.

另外，如果x射线源是一个双星系统，当x射线源被它的伴星所遮挡时，发出的x射线就会周期性地被切断。

The black holes are separated by an estimated distance of less than a third of a light-year - cheek-to-cheek by black hole standards and significantly closer than the postulated binary system spotted by the Chandra X-ray Observatory in 2003.
