Longitudinal drift of Tayler instability eigenmodes as a possible explanation for super-slowly rotating Ap stars
L. L. Kitchatinov, I. S. Potravnov, A. A. Nepomnyashchikh
Rotation periods inferred from the magnetic variability of some Ap stars are incredibly long, exceeding ten years in some cases. An explanation for such slow rotation is lacking. T…
Modelling differential rotation of red giants: the case of the evolved sun
Leonid Kitchatinov, Alexander Nepomnyashchikh
Asteroseismology has revealed that cores of red giants rotate about one order of magnitude faster than their convective envelopes. This paper attempts an explanation for this rotat…
Can the long-term hemispheric asymmetry of solar activity result from fluctuations in dynamo parameters?
Alexander Nepomnyashchikh, Sudip Mandal, Dipankar Banerjee +1
The hemispheric asymmetry of sunspot activity observed possesses a regular component varying on a time scale of several solar cycles whose origin and properties are currently debat…
Solar cycle asymmetry as a consequence of fluctuations in dynamo parameters
Leonid Kitchatinov, Alexander Nepomnyashchikh
The duration of activity growths in solar cycles is on average shorter than the duration of its declines. This asymmetry can result from fluctuations in dynamo parameters. A solar…
Modelling variability of solar activity cycles
L. L. Kitchatinov, A. V. Mordvinov, A. A. Nepomnyashchikh
Context. Solar activity cycles vary in amplitude and duration. The variations can be at least partly explained by fluctuations in dynamo parameters. Aims. We want to restrict uncer…
How supercritical are stellar dynamos, or why do old main-sequence dwarfs not obey gyrochronology?
Leonid Kitchatinov, Alexander Nepomnyashchikh
Asteroseismological determinations of stellar ages have shown that old main-sequence dwarfs do not obey gyrochronology. Their rotation is slow compared to young stars but faster th…
