摘要

Centaurus X-3 is a well studied high-mass accreting X-ray binary and a variable source of high-energy gamma rays with energies from 100 MeV to 1 TeV. Previous results have suggested that the origin of the gamma rays is not the immediate vicinity of the neutron star but is sited in the accretion disk, perhaps in an accretion wake. The Durham Mark 6 gamma-ray telescope has been used to measure the gamma-ray flux from Centaurs X-3 with much higher sensitivity than previous ground-based measure- ments. The flux above ~400 GeV was measured to be (2±0.3) X 10~-11 cm~-2s~-1 and appears constant over a period of 2-3 months.
