    Summary
    We discuss theimplications of therecent X-ray and TeV γ-ray observations of thePSRB1259-63 system (a young rotation powered pulsar orbiting a Be star) for thetheoretical models of interaction of pulsar and stellar winds. We show that previously considered models have problems to account for the observed behaviour of thesystem. We develop amodel in which thebroad band emission from thebinary system is produced in result of collisions of GeV-TeV energy protons accelerated by thepulsar wind and interacting with thestellar disk. In this model thehigh energy γ-rays are produced in thedecays of secondary neutral pions, while radio and X-ray emission are synchrotron and inverse Compton emission produced by low-energy (≤100MeV) electrons from thedecays of secondary charged π ± mesons. This model can explain not only theobserved energy spectra, but also thecorrelations between TeV, X-ray and radio emission components
