Double ring algorithm of solar active region eruptions within the framework of kinematic dynamo model

TL;DR

This paper introduces a new solar dynamo model that simulates poloidal field creation through double-ring structures, aiming to better align with observed solar cycle physics.

Contribution

It develops a physically consistent dynamo model using double-ring structures for poloidal field generation, improving upon previous alpha-effect parametrizations.

Findings

Preliminary results show promising alignment with observed solar cycle features.

The double-ring approach offers a more realistic representation of flux emergence.

The model advances understanding of magnetic flux dispersal in the solar cycle.

Abstract

Recent results indicate that the Babcock-Leighton mechanism for poloidal field creation plays an important role in the solar cycle. However, modelling this mechanism has not always correctly captured the underlying physics. In particular, it has been demonstrated that using a spatially distributed near-surface alpha-effect to parametrize the Babcock-Leighton mechanism generates results which do not agree with observations. Motivated by this, we are developing a physically more consistent model of the solar cycle in which we model poloidal field creation by the emergence and flux dispersal of double-rings structures. Here we present preliminary results from this new dynamo model.
