Scientific paper

The first evidence that the 283-s neutron star in the X-ray binary Vela X-1 radiates steady, pulsed TeV gamma rays with a sinusoidal light curve is presented. This is also the first evidence that a wind-driven binary system radiates in this energy range. A periodic enhancement was also observed which was in phase with the steady pulsed emission and eight times stronger. This event was directly observable as an enhancement in the counting rate of the telescope and occurred while the pulsar was entering eclipse. This is considered to be an indication that the enhancement was caused by gamma ray production by a charged-particle beam interacting with the limb of the companion star. This fact further indicates that TeV gamma rays are not produced on the neutron star itself but in the accreting material in the system.
