Measurements of the Perpendicular Correlation Length of Coronal Alfvénic Waves with DKIST

The Astrophysical Journal
We have measured the perpendicular correlation length L _⊥ of Alfvénic waves in the corona using data from the Daniel K. Inouye Solar Telescope (DKIST) Cryogenic Near Infrared Spectropolarimeter (Cryo-NIRSP) instrument.

Interaction of minor ions with fast and slow shocks [PDF]

The coronal slow shock was predicted to exist embedded in large coronal holes at 4 to 10 solar radii. A three-fluid model was used to study the jumps in minor ions propertes across the coronal slow shock.

Multiple Episodes of Remote Brightenings Driven by a Coronal Extreme-ultraviolet Jet on the Sun

The Astrophysical Journal
Remote brightening (RB) is compact brightening at footpoints of magnetic loops, which are remotely connecting to and confining an eruption in the solar atmosphere.

Enhanced Nonthermal Line Broadening inside Coronal Cavities above Solar Prominences Revealed by Spectral Imaging CoronaGraph

The Astrophysical Journal Letters
Coronal cavities, often associated with prominences, are crucial structures in understanding coronal heating and the eruption mechanism of coronal mass ejections.

Two Distinctly Different Characteristics of Flare-driven Coronal Rain Revealed from High-resolution Spectroscopic Imaging Observations with FISS/GST

The Astrophysical Journal
We report on a flare-driven coronal rain event observed along postflare loops during the decay phase of an X1.6-class solar flare. Although high-resolution studies of flare-driven coronal rain have been conducted, imaging spectroscopic studies are rare ...
