Multiwavelength observations of PSR B1259-63 periastron passage in 2010-2011
Abstract
PSR B1259-63 is a unique binary system with a radio pulsar from which unpulsed X-ray, gamma-ray, and radio emission was observed. The pulsar is in a highly eccentric 3.4 year orbit around a Be star. Collision of the pulsar wind with the wind of Be star plays a crucial role in generation of the observed emission. The goal of this proposal is to investigate, for the first time, simultaneous X-ray (XMM-Newton) and GeV gamma-ray (Fermi) spectral evolution of the system as the pulsar passes through the Be star disk. Details of the X-ray/gamma-ray spectral evolution will allow to probe the physical mechanism(s) of particle acceleration and interactions during collision of relativistic pulsar wind with the wind from the massive star.
