Query: Broadband spectroscopy using two Suzaku observation of the HMXB GX 301-2   We present the analysis of two Suzaku observations of GX 301-2 at two orbital
phases after the periastron passage. Variations in the column density of the
line-of-sight absorber are observed, consistent with accretion from a clumpy
wind. In addition to a CRSF, multiple fluorescence emission lines were detected
in both observations. The variations in the pulse profiles and the CRSF
throughout the pulse phase have a signature of a magnetic dipole field. Using a
simple dipole model we calculated the expected magnetic field values for
different pulse phases and were able to extract a set of geometrical angles,
loosely constraining the dipole geometry in the neutron star. From the
variation of the CRSF width and energy, we found a geometrical solution for the
dipole, making the inclination consistent with previously published values.
