Newly Observed Small-Scale Structures in the Quiet Sun and Their Connection to Solar Oscillations
Aleksandra Andic

TL;DR
This study uses high-resolution observations from the NST to identify small-scale structures in the quiet Sun and explores their relationship with solar oscillations, revealing that oscillation power concentrates near bright-point like features.
Contribution
The paper presents new high-resolution observations of small-scale quiet Sun structures and their connection to solar oscillations, exploiting NST's capabilities.
Findings
Bright-point like structures are prevalent in intergranular lanes.
Solar oscillations with maximum power are associated with these structures.
Oscillation power tends to concentrate near certain bright features.
Abstract
Our observations of the quiet Sun with the NST have yielded unanticipated results on smal-scale solar dynamic. Althought small-scale solar dynamic have been well-studied, the NST is enabling us to probe finer scale dynamic exploiting higher spatial resolution. We discuss NST resutls from data taken 29th July 2009 using an broadband filter centered on TiO 705.7nm spectral line. Data are from the center of the solar disk where we observed quiet Sun. We registered bright-point like structures in most of the intergranular lanes. They vary in behaviour and evolution. Co-registered solar oscillations tend to congregate near certain types of bright-point like structures. The oscillations with maximum power tend to appear only above or near these structures.
