Findings

Spectropolarimetric measurements reveal magnetic perturbations associated with FIP-related waves.

Stokes V amplitude asymmetries can serve as effective diagnostics for wave activity.

The method enhances understanding of wave influence on coronal plasma composition.

Abstract

High-resolution spectropolarimetry has opened new avenues for understanding how chromospheric waves shape coronal plasma composition. All modeling efforts so far highlight wave activity and, in particular, the ponderomotive force associated to Alfv\'enic perturbations, as a key ingredient. Over recent years, studies based on spectropolarimetric measurements in the solar chromosphere have identified magnetic perturbations associated to waves linked to regions in the corona with enhanced FIP bias. Building on this established framework, the present work explores the diagnostic potential of Stokes V amplitude asymmetries as an alternative diagnostic tool for investigating wave behavior relevant to compositional fractionation processes.
