摘要
Abstract We illustrate the evolution of the peculiar behavior of the high mass X-ray binary GX 301-2, through the wind accretion model. We found that the donor of this system has 43 M⨀ and clearly it experienced of a mass exchange. As a result, the low terminal velocity of the wind from donor (1200 km/s), slow rotation and the relatively low luminosity (3.1×1035erg/s), can easily fed the neutron star via the stellar wind with enough accretion matter. This will lead to explain the observed X-rays. It has been shown that the characteristics of mass-loss rate through stellar winds would reasonably be expected to alter the changes in wind velocity by X-rays.
