英文摘要We report on the results of the extensive multi-wavelength campaign from optical to gev gamma-rays of the 2014 periastron passage of psr b1259-63, which is a unique high-mass gamma-ray emitting binary system with a young pulsar companion. observations demonstrate the stable nature of the post-periastron gev flare and prove the coincidence of the flare with the start of rapid decay of the ha equivalent width, usually interpreted as a disruption of the be stellar disc. intensive x-ray observations reveal changes in the x-ray spectral behaviour happening at the moment of the gev flare. we demonstrate that these changes can be naturally explained as a result of synchrotron cooling of monoenergetic relativistic electrons injected into the system during the gev flare.
