The origin of dark lane on sunspot’s light bridge
Scientific ReportsLight bridges (LBs), embedded in sunspots, appear as elongated narrow bright features, in contrast to the surrounding dark sunspot umbra or penumbra. Under high-resolution observations, dark lanes were reported along the spine of LBs.

Exploring Solar Granulation: from IMaX/SUNRISE to DKIST
Proceedings of the International Florida Artificial Intelligence Research Society ConferenceGranules are small cellular structures that populate the solar photosphere and are formed by the dynamic behavior of convection cells. This constant motion generates an evolving pattern of diverse granule types and intergranular regions across the ...

Assessment of DKIST/VTF capabilities for the detection of local acoustic source wavefronts
Frontiers in Astronomy and Space SciencesIntroductionRecent studies have demonstrated that temporal filtering can successfully identify local acoustic source wavefronts in radiative magnetohydrodynamic simulations of the solar photosphere.

Origin of Line Broadening in Fading Granules: Influence of Small-scale Turbulence
The Astrophysical JournalIn the quiet region of the solar photosphere, turbulent convective motions of the granular flows naturally drive the subgranular-scale flows. However, evaluating such small-scale velocities is challenging because of the limited instrumental resolution ...
