In the present paper we consider the problem of resonance line polarizationformed in the spherically symmetric expanding atmospheres. For the solution ofthe concerned polarized transfer equation we use the comoving frameformulation, and apply the Accelerated Lambda Iteration (ALI) method. Werestrict ourselves to the non-relativistic regime of velocities wherein mainlyDoppler shift effects are significant. For our studies, we consider thescattering on a two-level atom, including the effects of partial frequencyredistribution (PFR). We present the dependence of linearly polarized profileson different atmospheric and atomic parameters.
