Cycles on the Solar-Type Stars and Cooler Dwarfs
N. I. Bondar, M. M. Katsova, M. A. Livshits
Features of the development of activity cycles in the solar-type stars and fast-rotating cool dwarfs have been considered for 65 stars observed in some decades. Cycles with duratio…
Can superflares occur on the Sun? A view from dynamo theory
M. M. Katsova, L. L. Kitchatinov, M. A. Livshits +3
Recent data from the Kepler mission has revealed the occurrence of superflares in sun-like stars which exceed by far any observed solar flares in release of energy. A natural idea…
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…
Evidence of the Relationship between the Emerging Magnetic Fields, Electric Currents, and Solar Flares Observed on May 10, 2012
M. A. Livshits, I. Yu. Grigoryeva, I. I. Myshyakov +1
We have analyzed multi-wavelength observations and magnetic-field data for the solar flare of May 10, 2012 (04:18 UT) and have detected a sign inversion of the signal in the line-o…
The Origin of Superflares on G-Type Dwarf Stars of Various Ages
M. M. Katsova, M. A. Livshits
We analyze new observations of superflares on G-stars discovered in the optical and near IR ranges with the Kepler mission. An evolution of solar-type activity is discussed. We giv…
Solar-Type Activity: Epochs of Cycle Formation
M. M. Katsova, N. I. Bondar', M. A. Livshits
The diagram of indices of coronal and chromospheric activity allowed us to reveal stars where solar-type activity appears and regular cycles are forming. Using new consideration of…
Activity and the Li abundances in the FGK dwarfs
T. V. Mishenina, C. Soubiran, V. V. Kovtyukh +2
The aim of the present study is to determine the Li abundances for a large set of the FGK dwarfs and to analyse the connections between the Li content, stellar parameters, and acti…
