FRADO吸积盘的质量损失率

Mass loss rate of accretion disk in FRADO

Mohammad-Hassan Naddaf, Bozena Czerny

摘要:

我们已经开发了Czerny & Hryniewicz(2011)的基本物理驱动的1D模型的2.5D版本,即失败的辐射加速尘埃外流(FRADO)模型。这个模型是基于这样的想法,即辐射压力作用于尘埃是负责的宽线区(BLR)的低电离部分的形成。这样的辐射压力足以在低电离BLR内部形成从盘表面的快速流出。流出性质取决于基本的物理参数,如黑洞质量,爱丁顿比和气体金属丰度。在这里,我们的目的是估计磁盘的质量损失率,由于这一过程中,并与宽吸收线(BAL)类星体中检测到的流出的结果进行比较。

英文摘要:

We have developed the 2.5D version of the basic physically motivated 1D model of Czerny & Hryniewicz (2011), i.e. Failed Radiatively Accelerated Dusty Outflow (FRADO) model. This model is based on the idea that radiation pressure acting on dust is responsible for the formation of the low ionized part of the Broad Line Region (BLR). Such radiation pressure is strong enough to form a fast outflow from the disk surface in the inner part of low ionized BLR. The outflow properties depend on the basic physical parameters, like black hole mass, Eddington ratio and gas metallicity. We here aim at estimating the disk mass loss rate due to this process, and comparing the results with outflows detected in Broad Absorption Line (BAL) quasars.
