Steady-state Heating of Diffuse Coronal Plasma in a Solar Active Region
The Astrophysical JournalThe solar corona is much hotter than lower layers of the solar atmosphere—the photosphere and chromosphere. The coronal temperature is up to 1 MK in quiet Sun areas, while up to several megakelvins in active regions, which implies a key role of the ...

Comparative Analysis of Ellerman and Quiet Sun Ellerman Bombs in the Solar Atmosphere
The Astrophysical JournalEllerman bombs (EBs) and quiet-Sun Ellerman bombs (QSEBs) are small-scale signatures of magnetic reconnection in the lower solar atmosphere, observed in active regions and quiet-Sun areas, respectively. We investigate and compare some of their properties
