Evolution of small-scale magnetic elements in the vicinity of granular-size swirl convective motions

TL;DR

This study investigates how small-scale magnetic elements and bright points evolve near convective vortex motions in the solar atmosphere, revealing their dynamic interactions and possible convective collapse events using high-resolution solar data.

Contribution

It provides new insights into the influence of vortex-type plasma motions on magnetic features and bright points in the quiet Sun, highlighting their evolution and underlying physical processes.

Findings

Magnetic features are affected by vortex plasma motions.

Bright points show intensity variations linked to vortex dynamics.

Possible convective collapse events are identified in Stokes profiles.

Abstract

Advances in solar instrumentation have led to a widespread usage of time series to study the dynamics of solar features, specially at small spatial scales and at very fast cadences. Physical processes at such scales are determinant as building blocks for many others occurring from the lower to the upper layers of the solar atmosphere and beyond, ultimately for understanding the bigger picture of solar activity. Ground-based (SST) and space-borne (Hinode) high-resolution solar data are analyzed in a quiet Sun region displaying negative polarity small-scale magnetic concentrations and a cluster of bright points observed in G-band and Ca II H images. The studied region is characterized by the presence of two small-scale convective vortex-type plasma motions, one of which appears to be affecting the dynamics of both, magnetic features and bright points in its vicinity and therefore the main target of our investigations. We followed the evolution of bright points, intensity variations at different atmospheric heights and magnetic evolution for a set of interesting selected regions. A description of the evolution of the photospheric plasma motions in the region nearby the convective vortex is shown, as well as some plausible cases for convective collapse detected in Stokes profiles.
