SEARCHING FOR COHERENT X-RAY PULSATIONS FROM TRANSIENT NUETRON STAR LMXBS


ABSTRACT

We will conduct quasi-simulataneous X-ray, optical, and radio observations of soft transient X-ray sources to search for coherent pulsations from the neutron star. In the pulsation searches in X-ray wavelengths, it is crucial to have strong constraints on the orbital elements, which we will obtain optical observations. At radio wavelengths we will also search for pulsations, which is of importance from evolutionary senario of the neutron star and its magnetic field.
