论文摘要
在本文中，我们考虑了在球形对称扩展大气中形成的共振线极化的问题。对于相关的极化转移方程的解决方案，我们使用共同的框架公式，并应用加速的lambda迭代（ALI）方法。我们将自己限制在速度的非权威主义方向上，其中主要是多普勒转移效应很大。在我们的研究中，我们考虑在两级原子上的散射，包括部分频率重新分布（PFR）的影响。我们介绍了线性极化轮廓对不同大气和原子参数的依赖性。
In the present paper we consider the problem of resonance line polarization formed in the spherically symmetric expanding atmospheres. For the solution of the concerned polarized transfer equation we use the comoving frame formulation, and apply the Accelerated Lambda Iteration (ALI) method. We restrict ourselves to the non-relativistic regime of velocities wherein mainly Doppler shift effects are significant. For our studies, we consider the scattering on a two-level atom, including the effects of partial frequency redistribution (PFR). We present the dependence of linearly polarized profiles on different atmospheric and atomic parameters.
