Centaurus X-3 (4U 1118-60) is an X-ray pulsar with a period of 4.84 seconds. It was the first X-ray pulsar to be discovered and the third X-ray source to be discovered in the constellation Centaurus. The system consists of a neutron star orbiting a massive O-type supergiant star dubbed Krzeminski’s star after its discoverer. Matter is being accreted from the star onto the neutron star resulting in X-ray emission.
