PRD effects on polarized lines formed in moving media in the presence of a weak magnetic field
M. Sampoorna and K. N. Nagendra Indian Institute of Astrophysics, Koramangala, Bengaluru, India
• We study the effect of macroscopic vertical velocity fields on the scattering line polarization profiles including the effects of partial frequency redistribution (PRD) and a weak magnetic field (Hanle effect).
• We consider a 1-D planar isothermal atmosphere with velocity field υz along the atmospheric normal.
• We show that the presence of a vertical velocity gradients enhances the linear polarization, produces a Doppler shift, and asymmetric line profiles (see Carlin et al. 2012).
• We show that, AD-PRD effects are important in a moving atmosphere with velocity gradients for both non-magnetic and magnetic cases.
