Activity of Selected Solar Twins
M. M. Katsova, B. A. Nizamov, A. A. Shlyapnikov
We analyze various tracers of magnetic activity for 23 solar twins which are characterized by significant scatter of lithium abundance in their atmospheres. A level of coronal and…
Multiwavelength Stereoscopic Observation of the May 1, 2013 Solar Flare and CME
Erica Lastufka, Säm Krucker, Ivan Zimovets +7
A M-class behind-the-limb solar flare on 1 May 2013 (SOL2013-05-01T02:32), accompanied by a ( 400 km/s) CME was observed by several space-based observatories with different v…
Soft X-ray heating as a mechanism of optical continuum generation in solar-type star superflares
B. A. Nizamov
Superflares on the solar type stars observed by \textit{Kepler} demonstrate the contrast in the optical continuum of the order 0.1--1 per cent. The mechanism of formation of this r…
Properties of Kepler Stars with the Most Powerful Flares
M. M. Katsova, B. A. Nizamov
We analyze physical characteristics of late-type stars wherein the Kepler mission registered superflares. We use the revised stellar fundamental parameters, i.e. effective temperat…
Radio, Hard X-Ray, and Gamma-Ray Emissions Associated with a Far-Side Solar Event
V. V. Grechnev, V. I. Kiselev, L. K. Kashapova +9
The SOL2014-09-01 far-side solar eruptive event produced hard electromagnetic and radio emissions observed with detectors at near-Earth vantage points. Especially challenging was a…
New estimation of non-thermal electron energetics in the giant solar flare on 28 October 2003 based on Mars Odyssey observations
B. A. Nizamov, I. V. Zimovets, D. V. Golovin +5
A new estimation of the total number and energy of the non-thermal electrons produced in the giant () solar flare on 2003 October 28 is presented based on the analysis…
Catalog of Hard X-ray Solar Flares Detected with Mars Odyssey/HEND from the Mars Orbit in 2001-2016
M. A. Livshits, I. V. Zimovets, D. V. Golovin +7
The study of nonstationary processes in the Sun is of great interest, and lately, multiwavelength observations and registration of magnetic fields are carried out by means of both…
Change in activity character of coronae of low-mass stars of various spectral types
B. A. Nizamov, M. M. Katsova, M. A. Livshits
We study the dependence of the coronal activity index on the star's rotation rate. This question was considered earlier for 824 late-type stars on the basis of a consolidated catal…
Superflare G and K Stars and the Lithium abundance
M. M. Katsova, M. A. Livshits, T. V. Mishenina +1
We analyzed here the connection of superflares and the lithium abundance in G and K stars based on Li abundance determinations conducted with the echelle spectra of a full set of 2…
