Using Suzaku observations we have examined the energy dependence of the pulsations upto highest detectable energies in these sources and compare the energy dependence with the X-ray luminosity and the magnetic field strength of these sources, if known. Similarly, the hard X-ray spectral properties of the sources are examined against the X-ray luminosity and the magnetic field strength. These measurements give valuable insight into physical properties of the emission region in accreting pulsars. In the lower energy band, we measured the emission lines, the absorbing column density, and the reprocessed soft X-ray emission. All of these together show the variety of the physical environment in the X-ray pulsars. |
