Ubiquitous high-frequency waves and disturbances in the active region corona observed with DKIST/Cryo-NIRSP

Momchil E. Molnar, Richard Morton, Alin Paraschiv +4

The plasma of the solar corona harbors a multitude of coronal wave modes, some of which could be dissipated to provide the required energy and momentum to heat the corona and accel…

Atmospheric Gravity Waves Modulated by the Magnetic Field Configuration

Oana Vesa, Julio Morales, Jason Jackiewicz +2

Atmospheric gravity waves (AGWs) are buoyancy-driven waves excited by turbulent convection and contribute to the dynamics and energy transport of the lower solar atmosphere. We pre…

Unveiling Unprecedented Fine Structure in Coronal Flare Loops with the DKIST

Cole A. Tamburri, Maria D. Kazachenko, Gianna Cauzzi +8

We present the highest-resolution H observations of a solar flare to date, collected during the decay phase of an X1.3-class flare on 8 August 2024 at 20:12 UT. Observations wi…

The striated solar photosphere observed at 0."03, resolution

D. Kuridze, F. Wöger, H. Uitenbroek +5

Striated granular edges observed in the solar photosphere represent one of the smallest-scale phenomena on the Sun. They arise from the interaction of strongly coupled hydrodynamic…
