Variabilities in the polar field and solar cycle due to irregular properties of Bipolar Magnetic Regions
Pawan Kumar, Bidya Binay Karak, Anu Sreedevi
Decay and dispersal of the tilted Bipolar Magnetic Regions (BMRs) on the solar surface are observed to produce large-scale poloidal field, which acts as the seed for the toroidal f…

Characterizing the solar cycle variability using nonlinear time series analysis at different amounts of dynamo supercriticality: Solar dynamo is not highly supercritical
Aparup Ghosh, Pawan Kumar, Amrita Prasad +1
The solar dynamo is essentially a cyclic process in which the toroidal component of the magnetic field is converted into the poloidal one and vice versa. This cyclic loop is distur…

Solar cycle variability induced by stochastic fluctuations of BMR properties and at different amounts of dynamo supercriticality
Pawan Kumar
Understanding the irregular variation of the solar cycle is crucial due to its significant impact on global climates and the heliosphere. Since the polar magnetic field determines…
