摘要:

我们提出了初步的结果和观测的微类星体模型的基础上的理论框架,静止的,强大的,紧凑的喷气发动机,然后从内部磁化磁盘加速。该模型旨在提供微类星体在所有光谱状态下的一致图像。它由一个外标准吸积盘组成,向下到一个可变的过渡半径,在那里它变成一个磁化盘,称为喷流发射盘(JED)。在给出加热的理论框架下,我们求解了辐射平衡,得到了JED结构。我们的JED解决方案是丰富的,并复制了已知的方案,其中冷光学厚和热光学薄的解决方案包括热不稳定的解决方案。本文给出了模型和初步结果,这是首次尝试再现XTE J1118+480的观测SED。

英文摘要:

We present preliminary results and observables from a model of microquasar based on a theoretical framework where stationary, powerful, compact jets are launched and then accelerated from an inner magnetized disk. This model aim at providing a consistent picture of microquasars in all their spectral states. It is composed of an outer standard accretion disk down to a variable transition radius where it changes to a magnetized disk, called the Jet Emitting Disk (JED). The theoretical framework providing the heating, we solve the radiative equilibrium and obtain the JED structure. Our JED solutions are rich, and reproduce the already known scheme where a cold optically-thick and a hot optically-thin solutions bracket a thermally unstable one. We present the model and preliminary results, whith a first attempt at reproducing the observed SED of XTE J1118+480.
