论文摘要
我们研究了在恒星质量黑洞周围的薄积盘中的风以及这些风在存在由增生盘产生的辐射场的情况下的时间演变。风是由辐射，热压和盘的离心力产生的。发现风度有些相对论，速度达到终端速度为0.1美元的增生率$ 4 $ $ 4 $。我们表明，弹出物质通过将角动量从圆盘传输到风来旋转。我们还表明，辐射阻力以非常重要的方式影响增生盘风。不仅由于辐射阻力导致的数量级，终端速度不仅降低，而且我们还表明，辐射阻力的非线性效应可以减轻从积聚盘弹出的风中形成风的形成。随着辐射阻力降低了风的速度，在存在下，质量流出速率也会降低。
We study the ejection of winds from thin accretion discs around stellar mass black holes and the time evolution of these winds in presence of radiation field generated by the accretion disc. Winds are produced by radiation, thermal pressure and the centrifugal force of the disc. The winds are found to be mildly relativistic, with speeds reaching up to terminal speeds $0.1$ for accretion rate $4$ in Eddington units. We show that the ejected matter gets its rotation by transporting angular momentum from the disc to the wind. We also show that the radiation drag affects the accretion disc winds in a very significant manner. Not only that the terminal speeds are reduced by an order of magnitude due to radiation drag, but we also show that the non-linear effect of radiation drag, can mitigate the formation of the winds from the matter ejected by the accretion disc. As radiation drag reduces the velocity of the wind, the mass outflow rate is reduced in its presence as well.
