Noun
LMXB (plural LMXBs)
(astronomy) Initialism of low-mass X-ray binary: a binary star system that is strong in X-rays, and in which the normal stellar component is a main sequence star, degenerate dwarf, or evolved star from the main sequence, and the compact X-ray emitting component is a neutron star, black hole, or white dwarf
Thus, we find the scenario of a very high inclination angle to be less plausible than the tMSP or BH LMXB models discussed above. Source: Internet
