Speaker: Supriya Dayananda

We have developed P-CORONA, a new three-dimensional (3D) modeling tool designed to investigate the polarization profiles of various solar coronal lines—both forbidden and permitted. This code takes into account the complexities introduced by magnetic fields, through both the Hanle and Zeeman effects, and non-radial solar wind velocities in a 3D coronal model. In this talk, I will describe the technical aspects of P-CORONA, which will soon be made accessible to the scientific community. Along with this, I will discuss some of the results obtained using P-CORONA, focusing specifically on the impact of non-radial solar wind velocities on the permitted Ly-α lines of H I and He II, and the forbidden lines of Fe XIII at 10747 Å and 10798 Å.
