Hysteresis between distinct modes of turbulent dynamos

Bidya Binay Karak, Leonid L. Kitchatinov, Axel Brandenburg

Nonlinear mean-field models of the solar dynamo show long-term variability, which may be relevant to different states of activity inferred from long-term radiocarbon data. This pap…

Correlation between Decay Rate and Amplitude of Solar Cycles as Revealed from Observations and Dynamo Theory

Gopal Hazra, Bidya Binay Karak, Dipankar Banerjee +1

Using different proxies of solar activity, we have studied the following features of solar cycle. (i) A linear correlation between the amplitude of cycle and its decay rate, (ii) a…

Polar Network Index as a magnetic proxy for the solar cycle studies

Muthu Priyal, Dipankar Banerjee, Bidya Binay Karak +4

The Sun has a polar magnetic field which oscillates with the 11 year sunspot cycle. This polar magnetic field is an important component of the dynamo process which is operating in…

Magnetically controlled stellar differential rotation near the transition from solar to anti-solar profiles

Bidya Binay Karak, Petri J. Kapyla, Maarit J. Kapyla +3

Late-type stars rotate differentially owing to anisotropic turbulence in their outer convection zones. The rotation is called solar-like (SL) when the equator rotates fastest and a…

Quenching and anisotropy of hydromagnetic turbulent transport

Bidya Binay Karak, Matthias Rheinhardt, Axel Brandenburg +2

Hydromagnetic turbulence affects the evolution of large-scale magnetic fields through mean-field effects like turbulent diffusion and the effect. For stronger fields, these eff…

A dynamo model of magnetic activity in solar-like stars with different rotational velocities

Bidya Binay Karak, Leonid L. Kitchatinov, Arnab Rai Choudhuri

We attempt to provide a quantitative theoretical explanation for the observations that Ca II H/K emission and X-ray emission from solar-like stars increase with decreasing Rossby n…
