Moving Magnetic Features around a Pore

TL;DR

This study analyzes the physical properties and dynamics of moving magnetic features near a solar pore using spectropolarimetric data, revealing their speeds, magnetic inclinations, and flux characteristics.

Contribution

It provides a detailed statistical analysis of MMFs around a pore, highlighting their velocities, magnetic field inclinations, and polarity-dependent flow patterns.

Findings

MMFs stream from the pore at ~1.2-1.3 km/s.

Opposite-polarity MMFs are blue-shifted.

Most MMFs are sub-arcsecond and carry flux ~1.2×10^{17} Mx.

Abstract

Spectropolarimetric observations from Sunrise II/IMaX obtained in June 2013 are used for a statistical analysis to determine the physical properties of moving magnetic features (MMFs) observed near a pore. MMFs of the same and opposite polarity with respect to the pore are found to stream from its border at an average speed of 1.3 km s$^{-1}$ and 1.2 km s$^{-1}$ respectively, with mainly same-polarity MMFs found further away from the pore. MMFs of both polarities are found to harbor rather weak, inclined magnetic fields. Opposite-polarity MMFs are blue-shifted, while same-polarity MMFs do not show any preference for up- or downflows. Most of the MMFs are found to be of sub-arcsecond size and carry a mean flux of $\sim$ 1.2$\times 10^{17}$ Mx.
