AbstractPSR B1259-63 is a 48 ms radio pulsar in a highly eccentric 3.4 year orbit with a Be star SS 2883. 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 and compare them with previous observations. With these data we are able, for the first time, to study the details of the spectral evolution of the source over a 2 months period of the passage of the pulsar close to the Be star. New data confirm the pre-periastron spectral hardening, with the photon index reaching a value smaller than 1.5. Such a behaviour can be explained within both synchrotron and IC model of the origin of the X-ray emission. Similarity of the form of rise and decay of the X-ray emission during the two disk passages and its resemblance to the radio lightcurve gives an argument in favour of the IC model.
