Probing the variations in the timing of the Sun's polar magnetic field reversals through observations and surface flux transport simulations
Elena M. Golubeva, Akash Biswas, Anna I. Khlystova +2
The polar field reversal is a crucial process in the cyclic evolution of the large-scale magnetic field of the Sun.Various important characteristics of a solar cycle, such as its d…
Synthetic solar cycle for active regions violating the Hale's polarity law
A. Zhukova, A. Khlystova, V. Abramenko +1
Long observational series for bipolar active regions (ARs) provide significant information about the mutual transformation of the poloidal and toroidal components of the global sol…
Evolution of the Sun's activity and the poleward transport of remnant magnetic flux in Cycles 21--24
Alexander V. Mordvinov, Bidya Binay Karak, Dipankar Banerjee +4
Detailed study of the solar magnetic field is crucial to understand its generation, transport and reversals. The timing of the reversals may have implications on space weather and…
Dynamo Model for North-South Asymmetry of Solar Activity
Leonid Kitchatinov, Anna Khlystova
Observations reveal a relatively small but statistically significant North-South (NS) asymmetry in sunspot activity varying on a time scale of several solar cycles. This paper prop…
A Catalog of Bipolar Active Regions Violating the Hale Polarity Law, 1989-2018
A. Zhukova, A. Khlystova, V. Abramenko +1
There is no list of bipolar active regions (ARs) with reverse polarity (anti-Hale regions), although statistical investigations of such ARs (bearing the imprint of deep subphotosph…
Long-Term Evolution of the Sun's magnetic field during Cycles 15--19 based on their proxies from Kodaikanal Solar Observatory
Alexander V. Mordvinov, Bidya Binay Karak, Dipankar Banerjee +3
The regular observation of the solar magnetic field is available only for about last five cycles. Thus, to understand the origin of the variation of the solar magnetic field, it is…
Photospheric Velocity Structures during the Emergence of Small Active Regions on the Sun
Anna Khlystova, Shin Toriumi
We study the plasma flows in the solar photosphere during the emergence of two small active regions, NOAA 9021 and 10768. Using SOHO/MDI data, we find that the strong plasma upflow…
Solar small-scale dynamo and polarity of sunspot groups
D. Sokoloff, A. Khlystova, V. Abramenko
In order to clarify a possible role of small-scale dynamo in formation of solar magnetic field, we suggest an observational test for small-scale dynamo action based on statistics o…
North-south asymmetry of solar dynamo in the current activity cycle
L. L. Kitchatinov, A. I. Khlystova
An explanation is suggested for the north-south asymmetry of the polar magnetic field reversal in the current cycle of solar activity. The contribution of the Babcock-Leighton mech…
The Relationship Between Plasma Flow Doppler Velocities and Magnetic Field Parameters During the Emergence of Active Regions at the Solar Photospheric Level
A. Khlystova
A statistical study has been carried out of the relationship between plasma flow Doppler velocities and magnetic field parameters during the emergence of active regions at the sola…
The Horizontal Component of Photospheric Plasma Flows During the Emergence of Active Regions on the Sun
A. Khlystova
The dynamics of horizontal plasma flows during the first hours of the emergence of active region magnetic flux in the solar photosphere have been analyzed using SOHO/MDI data. Four…
Center-limb dependence of photospheric velocities in regions of emerging magnetic fields on the Sun
A. Khlystova
We investigate the ratio of the vertical and horizontal velocities of the photospheric plasma flows in the region of emerging magnetic fields on the Sun. We carried out a study of…
