Estimate of the Upper Limit on Hot Plasma Differential Emission Measure (DEM) in Non-Flaring Active Regions and Nanoflare Frequency Based on the Mg XII Spectroheliograph Data from CORONAS-F/SPIRIT
Anton Reva, Artem Ulyanov, Alexey Kirichenko +2
The nanoflare-heating theory predicts steady hot plasma emission in the non-flaring active regions. It is hard to find this emission with conventional non-monochromatic imagers (su…

Nonlinear evolution of short-wavelength torsional Alfven waves
S. V. Shestov, V. M. Nakariakov, A. S. Ulyanov +2
We analyse nonlinear evolution of torsional Alfvén waves in a straight magnetic flux tube filled in with a low- plasma, and surrounded with a plasma of lower density. Such magne…
