Oscillatory behavior in the quiet Sun observed with the New Solar Telescope

TL;DR

This study uses high-resolution observations from the New Solar Telescope to analyze oscillatory behaviors in the quiet Sun, linking bright point-like structures and flux tubes to oscillatory events.

Contribution

It provides new insights into the spatial association between oscillations and bright structures in the quiet Sun at unprecedented resolution.

Findings

Oscillatory events are often located above bright point-like structures.

More powerful oscillations are cospatial with these bright structures.

Flux tubes may be the source of many observed oscillatory events.

Abstract

Surface photometry of the quiet Sun has achieved an angular resolution of $0".1$ with the New Solar Telescope at Big Bear Solar Observatory revealing that a disproportionate fraction of the oscillatory events appear above observed bright point-like structures. During the tracking of these structures, we noted that the more powerful oscillatory events are cospatial with them, indicating that observed flux tubes may be the source of many observed oscillatory events.
