论文摘要
本文介绍了结构的三维（3D）建模的结果，以及在柱底座中产生的光子的压力足以确定血浆流动的动力学的情况下，在表面上方形成的增生柱的发射。在数值辐射流体动力模拟的基础上，构建了几种3D积聚柱模型。模型的第一组包含空间3D列。相应的计算导致辐射通量在圆柱的侧壁上的分布，这些分布未以轴向对称为特征。第二组包括光谱辐射传递和列的二维空间结构的自洽建模，并考虑了热和散装组合。根据模型的物理参数，研究了列结构的变化和X射线连续体的形状。
The paper presents the results of three-dimensional (3D) modelling of the structure and the emission of accretion columns formed above the surface of accreting strongly magnetized neutron stars under the circumstances when a pressure of the photons generated in the column base is enough to determine the dynamics of the plasma flow. On the foundation of numerical radiation hydrodynamic simulations, several 3D models of accretion column are constructed. The first group of the models contains spatially 3D columns. The corresponding calculations lead to the distributions of the radiation flux over the sidewalls of the columns which are not characterized by axial symmetry. The second group includes the self-consistent modelling of spectral radiative transfer and two-dimensional spatial structure of the column, with both thermal and bulk Comptonization taken into account. The changes in the structure of the column and the shape of X-ray continuum are investigated depending on physical parameters of the model.
