摘要：
Spin evolution of the X-ray pulsar OAO 1657-415 in a wind-fed High Mass X-ray Binary (HMXB) is discussed. We suggest that its regular spin-up behaviour superposed with the spin-up/down episodes can be explained in terms of the Magnetic Levitation Accretion scenario (MLA scenario). This implies that the neutron star captures matter from a magnetized stellar wind of its massive companion. The magnetic field of the wind at a distance of the orbital separation within this scenario can be limited within the range of 20 - 70 mG.
