Enhancement of ionospheric heating effect by chemical release

Scientific Reports
The ionosphere can be artificially modified by employing ground-based high-power high-frequency electromagnetic waves to irradiate the ionosphere. This modification is achieved through the nonlinear interaction between the electromagnetic waves and the ...

Using a Differential Emission Measure and Density Measurements in an Active Region Core to Test a Steady Heating Model

, 2011
The frequency of heating events in the corona is an important constraint on the coronal heating mechanisms. Observations indicate that the intensities and velocities measured in active region cores are effectively steady, suggesting that heating events ...

Spatial and Temporal Distribution of Nanoflare Heating during Active Region Evolution

The Astrophysical Journal
Nanoflares are believed to be key contributors to heating solar nonflaring active regions, though their individual detection remains challenging. This study uses a data-driven field-aligned hydrodynamic model to examine nanoflare properties throughout ...
