| Abstract | From the extreme position of disk motion, we infer the neutron star (NS) surface magnetic field strength (B 0) of Z-source GX 17+2 and Cyg X-2. The inferred B 0 of GX 17+2 and Cyg X-2 are ~(1-5)¡Á108 G and ~(1-3)¡Á108 G, respectively, which are not inferior to that of millisecond X-ray pulsars or atoll sources. It is likely that the NS magnetic axis of Z sources is parallel to the axis of rotation, which could result in the lack of pulsations in these sources. |
