  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.
