Post-impulsive millimeter emission of the 2022-05-04 solar flare
G. G. Motorina, Yu. T. Tsap, V. V. Smirnova +2
The present work aims at analyzing the nature of millimeter (mm) emission observed during the post-impulsive phase of the solar flare SOL2022-05-04T08:45 (M5.7), detected by the RT…
Investigation of possible precursors of solar flares in the active region 12230 On December 9, 2014
G. G. Motorina, I. N. Sharykin, I. V. Zimovets +1
The question of the nature of precursors of solar flares, as well as their relationship with subsequent flares, still has no unambiguous answer. This is due, in particular, to the…
Flare heating of the chromosphere: Observations of flare continuum from GREGOR and IRIS
M. García-Rivas, J. Kašparová, A. Berlicki +8
Context: On 2022 May 4, an M5.7 flare erupted in the active region NOAA 13004, which was the target of a coordinated campaign between GREGOR, IRIS, Hinode, and ground-based instrum…
Pre-impulsive and Impulsive Phases of the Sub-Terahertz Flare of March 28, 2022
G. G. Motorina, Yu. T. Tsap, V. V. Smirnova +3
Properties of the solar radio spectrum, as well as the temporal profiles of flare emission, indicate the thermal nature of the sub-terahertz (sub-THz) component observed as the gro…
Measurements of strong magnetic fields in umbra of sunspots: Crimea vs Mt. Wilson
Yu. T. Tsap, V. A. Perebeynos, A. V. Borisenko +4
The comparative analysis for 1324 measurements of the corresponding sunspot magnetic fields with B > 2.5 kG (according to Crimean data) obtained at Crimean and Mt. Wilson observato…
Frequency rising sub-THz emission from solar flare ribbons
E. P. Kontar, G. G. Motorina, N. L. S. Jeffrey +3
Observations of solar flares at sub-THz frequencies (mm and sub-mm wavelengths) over the last two decades often show a spectral component rising with frequency. Unlike a typical gy…
Dynamics of plasma heating and energy distributions of accelerated electrons during solar flares based on X-ray and ultraviolet emission
Galina G. Motorina
The aim of the thesis is the study of properties of solar flares via reconstruction of energy distributions of accelerated/heated electrons, diagnostics of flare plasma based on EU…
On the origin of 140 GHz emission from the 4 July 2012 solar flare
Yuriy T. Tsap, Victoria V. Smirnova, Alexander S. Morgachev +4
The sub-THz event observed on the 4 July 2012 with the Bauman Moscow State Technical University Radio Telescope RT-7.5 at 93 and 140~GHz as well as Kislovodsk and Metsähovi radio t…
Differential Emission Measure and Electron Distribution Function Reconstructed from RHESSI and SDO Observations
G. G. Motorina, E. P. Kontar
To solve a number of problems in solar physics related to mechanisms of energy release in solar corona parameters of hot coronal plasma are required, such as energy distribution, e…
