Astrospheres and Cosmic Rays
A. Struminsky, A. Sadovski
An ionization plays a key role in formation of stars, planets and their atmospheres. Cosmic rays (CR) are the main source of the ionization, therefore it is important to know and b…
Magnetic structure of solar flare regions producing hard X-ray pulsations
I. V. Zimovets, R. Wang, Y. D. Liu +5
We present analysis of the magnetic field in seven solar flare regions accompanied by the pulsations of hard X-ray (HXR) emission. These flares were studied by Kuznetsov et al. (20…
Stellar Cosmic Rays in a Habitable Zone
Alexei Struminsky, Andrei Sadovski
According to recent observations relative number of flare stars does not change very much from cool dwarfs to hot A stars. Flare energies are strongly correlated with stellar lumin…
Cosmic Rays near Proxima Centauri b
Alexei Struminsky, Andrei Sadovski, Anatoly Belov
Cosmic rays are an important factor of space weather determining radiation conditions near the Earth and it seems to be essential to clarify radiation conditions near extrasolar pl…
Spatio-temporal dynamics of sources of hard X-ray pulsations in solar flares
S. A. Kuznetsov, I. V. Zimovets, A. S. Morgachev +1
We present systematic analysis of spatio-temporal evolution of sources of hard X-ray (HXR) pulsations in solar flares. We concentrate on disk flares whose impulsive phase are accom…
Properties of chromospheric evaporation and plasma dynamics of a solar flare from IRIS observations
Viacheslav M. Sadykov, Santiago Vargas Dominguez, Alexander G. Kosovichev +3
Dynamics of hot chromospheric plasma of solar flares is a key to understanding of mechanisms of flare energy release and particle acceleration. A moderate M1.0 class flare of 12 Ju…
Spatially resolved observations of a split-band coronal type-II radio burst
I. Zimovets, N. Vilmer, A. C. -L. Chian +2
Context. The origin of coronal type-II radio bursts and of their band-splitting are still not fully understood. Aims. To make progress in solving this problem on the basis of one e…
Non-Thermal "Burst-on-Tail" of Long-Duration Solar Event on 26 October 2003
I. V. Zimovets, A. B. Struminsky
Observations of a rare long-duration solar event of GOES class X1.2 from 26 October 2003 are presented. This event showed a pronounced burst of hard X-ray and microwave emission, w…
Instrumental oscillations in RHESSI count rates during solar flares
A. R. Inglis, I. V. Zimovets, B. R. Dennis +4
Aims: We seek to illustrate the analysis problems posed by RHESSI spacecraft motion by studying persistent instrumental oscillations found in the lightcurves measured by RHESSI's X…
Observations of quasi-periodic solar X-ray emission as a result of MHD oscillations in a system of multiple flare loops
I. V. Zimovets, A. B. Struminsky
We investigate the solar flare of 20 October 2002. The flare was accompanied by quasi-periodic pulsations (QPP) of both thermal and nonthermal hard X-ray emissions (HXR) observed b…
