The study of Hydrodynamical wind on the observational properties of magnetized accretion flow with thermal conduction

In this paper, we examine the effect of a hydrodynamical wind on the observational properties of supercritical accretion discs (slim discs) with thermal conduction in the presence of magnetic field under a self similar treatment. The disk gas is assumed to be isothermal. In this flow, the mass-accretion rate ? decreases with radius r as ? / r(s+12), where s is an arbitrary constant and indication of the effect of wind. Cooling effects of outflows or winds are noticeable in luminosity and effective temperature of advection dominated accretion flows. We apply this model to black-hole X-ray binary LMC X-3, which is supposed to be under critical accretion rate. Increasing the effect of wind decreases the disc’s temperature, luminosity and radiation flux of the disc, because of energy flux which is taken away by winds. The effect of thermal conduction is similar to the effect of wind in the disc’s temperature, luminosity and radiation flux of the disc, but the influence of wind on the observational properties is bigger than the effect of thermal conduction.
