Zusammenfassung:
PSR B1259-63 is a 48 ms radio pulsar in a highly eccentric 3.4 year orbit with a Be star SS 2883. Unpulsed γ-ray, X-ray and radio emission is observed from the binary system and the collision of the pulsar wind with the anisotropic wind of the Be star plays a crucial role in the generation of the observed emission. The 2007 periastron passage was observed in unprecedented details with Suzaku, Swift, XMM-Newton and Chandra missions. We present here the results of this campaign, compare them with previous observations and discuss the physical implications.
