Title	P868 - Simultaneous X-ray/radio observations of the mode-switching PSR B0943+10

Subject	Astronomical and Space Sciences not elsewhere classified

Description	Among the family of the neutron stars emitting pulsed signals in the radio band (the so called radio pulsars) there are some objects showing a peculiar behavior. In particular, the intensity and the properties of their pulsed radio emission change at unpredictable times between a status of relatively low emission (called Quiet, or Q mode) and a status of strong emission (called Burst or B mode) and then back to the Quiet mode. In the case of one of these pulsars, PSR B0943+10 (discovered back in 1969), it was recently shown that this swinging behavior is reproduced also in its emission in the much more energetic X-ray band, although with opposite relative emission fluxes with respect to the radio band, i.e. at strong radio emission corresponds fainter X-ray emission while at weaker radio emission corresponds brighter X-ray emission. This unexpected behavior makes PSR B0943+10 a primary target for a deeper understanding of the still largely obscure emission mechanisms of the neutron stars. Therefore a large program of additional simultaneous X-ray (with the XMM-Newton satellite) and radio (involving 5 telescopes around the continents) observations have been set up and the Parkes radio telescope will be part of this worldwide effort.
