Relative efficiency of three mechanisms of vector fields growth in a random media
E. A. Illarionov, D. D. Sokoloff
We consider a model of a random media with fixed and finite memory time with abrupt losses of memory (renovation model). Within the memory intervals we can observe either amplifica…
Clarifying Physical Properties of Magnetic Fields in Sunspots
V. N. Obridko, M. M. Katsova, D. D. Sokoloff +2
We demonstrate that the radial magnetic-field component at the outer boundary of the sunspot penumbra is about 550 Mx cm independent of the sunspot area and the maximum magn…
Finite memory time and anisotropy effects for initial magnetic energy growth in random flow of conducting media
E. A. Illarionov, D. D. Sokoloff
The dynamo mechanism is a process of magnetic field self-excitation in a moving electrically conducting fluid. One of the most interesting applications of this mechanism related to…
Magnetic fields in the accretion disks for various inner boundary conditions
Daniela V. Boneva, Evgeny A. Mikhailov, Maria V. Pashentseva +1
The magnetic fields of accretion disks play an important role in studying their evolution. We may assume that its generation is connected to the dynamo mechanism, which is similar…
Generation of strong magnetic fields in a nascent neutron star accounting for the chiral magnetic effect
Maxim Dvornikov, V. B. Semikoz, D. D. Sokoloff
We propose the mean field dynamo model for the generation of strongest magnetic fields, , in a neutron star (NS) accounting for the chiral magnetic effect (…
Dynamo generated magnetic configurations in accretion discs and the nature of quasi-periodic oscillations in accreting binary systems
David Moss, Dmitri Sokoloff, Valery Suleimanov
Magnetic fields are important for accretion disc structure. Magnetic fields in a disc system may be transported with the accreted matter. They can be associated with either the cen…
Magnetic and gaseous spiral arms in M83
P. Frick, R. Stepanov, R. Beck +4
Isotropic and anisotropic wavelet transforms are used to decompose the images of the spiral galaxy M83 in various tracers to quantify structures in a range of scales from 0.2 to 10…
A new dynamo pattern revealed by the tilt angle of bipolar sunspot groups
A. Tlatov, E. Illarionov, D. Sokoloff +1
We obtain the latitude-time distribution of the averaged tilt angle of solar bipoles. For large bipoles, which are mainly bipolar sunspot groups, the spatially averaged tilt angle…
Reversals of the solar dipole
David Moss, Leonid L. Kitchatinov, Dmitri Sokoloff
During a solar magnetic field reversal the magnetic dipole moment does not vanish, but migrates between poles, in contradiction to the predictions of mean-field dynamo theory. We t…
Multiscale magnetic fields in spiral galaxies: evolution and reversals
David Moss, Rodion Stepanov, Tigran Arshakian +3
Magnetic fields in nearby, star-forming galaxies reveal both large-scale patterns and small-scale structures. A large-scale field reversal may exist in the Milky Way but no such re…
The model of dynamo with small number of modes and magnetic activity of T Tauri stars
D. D. Sokoloff, S. N. Nefedov, A. A. Ermash +1
The model that describes operation of dynamo in fully convective stars is presented. It is based on representation of stellar magnetic field as a superposition of finite number of…
