摘要:

我们发展了一种基于L.B.用Lucy的不可分光子包方法计算了任意几何条件下康普顿化热等离子体的X射线连续谱,并用它描述了INTEGRAL观测到的银河系超吸积微类星体SS 433的宽频带X射线连续谱。本文提出了一个X射线发射区的物理模型,它包括来自吸积盘、喷流和热日冕的热发射,其中不同来源的光子被康普顿化。通过与INTEGRAL观测结果的比较,我们估算了SS 433复杂X射线发射区的物理参数,并给出了不同视角下的模型谱。

英文摘要:

We develop a Monte-Carlo technique based on L.B. Lucy's indivisible photon packets method to calculate X-ray continuum spectra of comptonized thermal plasma in arbitrary geometry and apply it to describe the broadband X-ray continuum of the galactic superaccreting microquasar SS433 observed by INTEGRAL. A physical model of the X-ray emitting region is proposed that includes thermal emission from the accretion disk, jets and hot corona where the photons of different origin are comptonized. From comparison with INTEGRAL observations, we estimate physical parameters of the complex X-ray emitting region in SS433 and present model spectra for different viewing angles of the object.
