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.

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.

Coronal Heating versus Solar Wind Acceleration

, 2004
Parker's initial insights from 1958 provided a key causal link between the heating of the solar corona and the acceleration of the solar wind. However, we still do not know what fraction of the solar wind's mass, momentum, and energy flux is driven by Parker-type gas pressure gradients, and what fraction is driven by, e.g., wave-particle interactions ...

. We review our recent results of global onedimensional (1-D) MHD simulations for the acceleration of solar and stellar winds. We impose transverse photospheric motions corresponding to the granulations, which generate outgoing Alfvén waves. We treat the

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.

Coupling of the solar wind, magnetosphere and ionosphere by MHD waves

, 2012
The solar wind, magnetosphere and ionosphere are coupled by magnetohydrodynamic waves, and this gives rise to new and often unexpected behaviours that cannot be produced by a single, isolated part of the system.
