TL;DR

This paper investigates how MHD waves in small-scale flux tubes produce observable signatures in spectropolarimetric data, using realistic simulations to understand their effects on Stokes profiles.

Contribution

It introduces a method to synthesize Stokes profiles from realistic flux tube simulations with propagating MHD waves, revealing their observational signatures.

Findings

MHD waves produce distinct signatures in Stokes profiles.

Non-linear wave propagation affects spectral line polarization.

Simulations help interpret spectropolarimetric observations of flux tubes.

Abstract

We present some results obtained from the synthesis of Stokes profiles in small-scale flux tubes with propagating MHD waves. To that aim, realistic flux tubes showing internal structure have been excited with 5 min period drivers, allowing non-linear waves to propagate inside the magnetic structure. The observational signatures of these waves in Stokes profiles of several spectral lines that are commonly used in spectropolarimetric measurements are discussed.
