Aquila X-1 (frequently abbreviated to Aql X-1) is a low-mass x-ray binary (LMXB) and the most luminous X-Ray source in the constellation Aquila. It was first observed by the satellite Vela 5B which detected several outbursts from this source between 1969 and 1976.[1] Its optical counterpart is variable, so it was named V1333 Aql according to the IAU standards. The system hosts a neutron star that accretes matter from a main sequence star of spectral type K4.[2] The binary's orbital period is 18.9479 hours.[3]

The neutron star radiation flux is slightly variable due to the nuclear burning of the accreted helium on the surface.[4]
