Coronal heating by waves [PDF]

, 1983
Alfven waves or Alfvenic surface waves carry enough energy into the corona to provide the coronal energy requirements. Coronal loop resonances are an appealing means by which large energy fluxes enter active region loops.

Rotation of Solar Chromosphere: A Global Perspective of Mg II Index during the Decay Phase of the Modern Maximum

The Astrophysical Journal
Rotation is one of the fundamental characteristics of the Sun, and it plays a crucial role in understanding the magnetic activities and dynamo processes.

Chromosphere of the quiet sun

Astronomy & Astrophysics
Context. The solar chromosphere is a dynamic and crucial interface between the solar interior and its interplanetary environment, regulating how energy is locally deposited into heat and transported into the upper atmospheric layers.

Generation and Life Cycle of Solar Spicules

The Astrophysical Journal
The physical mechanism for the creation of solar spicules is proposed with three stages of their life cycle. It is assumed that at stage I the density hump is formed locally in the x-y plane in the lower chromosphere in the presence of temperature ...

Insight into the Solar Plage Chromosphere with DKIST

The Astrophysical Journal
The strongly coupled hydrodynamic, magnetic, and radiation properties of the plasma in the solar chromosphere make it a region of the Sun's atmosphere that is poorly understood. We use data obtained with the high-resolution Visible Broadband Imager (VBI)

Alfvén Wave Heating of Solar Chromosphere Reexamined

The Astrophysical Journal
Models of heating the weakly ionized solar atmosphere by collisional damping of upward-propagating Alfvén waves, calculated under the assumption that only incompressible (intermediate-mode) MHD waves are involved, have predicted heating rates that do not
