Forecasting the solar activity cycle: new insights
Dibyendu Nandy, Bidya Binay Karak
Having advanced knowledge of solar activity is important because the Sun's magnetic output governs space weather and impacts technologies reliant on space. However, the irregular n…
Is a deep one-cell meridional circulation essential for the flux transport Solar Dynamo?
Gopal Hazra, Bidya Binay Karak, Arnab Rai Choudhuri
The solar activity cycle is successfully modeled by the flux transport dynamo, in which the meridional circulation of the Sun plays an important role. Most of the kinematic dynamo…
Studies of grand minima in sunspot cycles from a flux transport solar dynamo model
Bidya Binay Karak, Arnab Rai Choudhuri
We propose that grand minima in solar activity are caused by simultaneous fluctuations in the meridional circulation and the Babcock-Leighton mechanism for the poloidal field gener…
Dynamo in Protostar
Mahendra K. Verma, Bidya Binay Karak, Rohit Kumar
In this paper, we estimate the magnetic Reynolds number of a typical protostar before and after deuterium burning, and claim for the existence of dynamo process in both the phases,…
