An Intensive Multi-Wavelength Study of a Single Orbit of LSI +61 303
Abstract
LSI +61 303 is one of the few binary systems consisting of a compact object and Be star from which unpulsed X-ray and radio as well as strongly variable GeV and TeV gamma-ray emission has been observed. Previous RXTE monitoring of the source during one 26.5-day-long orbital cycle in 1996 revealed that the phase of X-ray maximum is shifted with respect to the phase of the radio maximum. It is known that the phase of the radio maximum drifts in a regular way with a period of 4.6 yr. We propose to perform a new series of observations covering one binary orbit designed to test a theoretical model based on a compactified pulsar wind nebula which explains both the shifts and the drifts of the phases of the maxima of radio, X-ray, and gamma-ray lightcurves.
