It introduces a new inversion code that models the Stokes profiles with comprehensive physical mechanisms, improving the inference of magnetic and plasma properties in the solar atmosphere.

Findings

Initial atmospheric and magnetic inversion results demonstrate the code's capabilities.

The code effectively accounts for quantum atomic effects and magnetic field influences.

Future developments aim to enhance the inversion accuracy and applicability.

Abstract

We present the Tenerife Inversion Code (TIC), which has been developed to infer the magnetic and plasma properties of the solar chromosphere and transition region via full-Stokes inversion of polarized spectral lines. The code is based on the HanleRT forward engine, which takes into account many of the physical mechanisms that are critical for a proper modeling of the Stokes profiles of spectral lines originating in the tenuous and highly dynamic plasmas of the chromosphere and transition region: quantum level population imbalance and interference (atomic polarization), frequency coherence effects in polarized resonance scattering (partial frequency redistribution), and the impact of arbitrary magnetic fields on the atomic polarization and the radiation field. We present first results of atmospheric and magnetic inversions, and discuss future developments for the project.
