Mean field models of flux transport dynamo and meridional circulation in the Sun and stars

G Hazra, D Nandy, L Kitchatinov, AR Choudhuri - Space Science Reviews, 2023 - Springer
The most widely accepted model of the solar cycle is the flux transport dynamo model. This
model evolved out of the traditional α Ω dynamo model which was first developed at a time …

Dynamo models of the solar cycle

P Charbonneau - Living Reviews in Solar Physics, 2020 - Springer
This paper reviews recent advances and current debates in modeling the solar cycle as a
hydromagnetic dynamo process. Emphasis is placed on (relatively) simple dynamo models …

Evolution of solar and stellar dynamo theory

P Charbonneau, D Sokoloff - Space Science Reviews, 2023 - Springer
In this paper, written as a general historical and technical introduction to the various
contributions of the collection “Solar and Stellar Dynamo: A New Era”, we review the …

World on data perspective

MKM Nasution - World, 2022 - mdpi.com
It is not simple to consider the world from only one side, but analyzing all sides can cloud
comprehension without reaching deep insight found at the core. In a word as a whole, there …

Solar cycle variability induced by tilt angle scatter in a Babcock–Leighton solar dynamo model

BB Karak, M Miesch - The Astrophysical Journal, 2017 - iopscience.iop.org
We present results from a three-dimensional Babcock–Leighton (BL) dynamo model that is
sustained by the emergence and dispersal of bipolar magnetic regions (BMRs). On average …

Impact of anomalous active regions on the large-scale magnetic field of the Sun

S Pal, P Bhowmik, SS Mahajan… - The Astrophysical …, 2023 - iopscience.iop.org
One of the major sources of perturbation in the solar cycle amplitude is believed to be the
emergence of anomalous active regions that do not obey Hale's polarity law and Joy's law of …

Solar evolution and extrema: current state of understanding of long-term solar variability and its planetary impacts

D Nandy, PCH Martens, V Obridko, S Dash… - Progress in Earth and …, 2021 - Springer
The activity of stars such as the Sun varies over timescales ranging from the very short to the
very long—stellar and planetary evolutionary timescales. Experience from our solar system …

Causality in heliophysics: magnetic fields as a bridge between the Sun's interior and the Earth's space environment

D Nandy, Y Baruah, P Bhowmik, S Dash… - Journal of Atmospheric …, 2023 - Elsevier
Our host star, the Sun, is a middle-aged main sequence G type star whose activity varies.
These variations are primarily governed by solar magnetic fields which are produced in the …
