DOI: 10.1007/s11207-024-02360-5

Abstract: In the Sun and solar-type stars, there is a critical dynamo number for the operation of a large-scale dynamo, below which the dynamo ceases to operate. This region is known as the subcritical region. Previous… read more here.

DOI: 10.1007/s11214-015-0204-5

Abstract: A number of observational and theoretical aspects of solar magnetoconvection are considered in this review. We discuss recent developments in our understanding of the small-scale structure of the magnetic field on the solar surface and… read more here.

DOI: 10.1063/1.5046842

Abstract: The statistical properties of the subgrid energy transfers of homogeneous small-scale dynamo are investigated during the kinematic, nonlinear and statistically saturated stages. We carry out an a priori analysis of data obtained from an ensemble… read more here.

DOI: 10.1093/mnrasl/slw190

Abstract: We consider kinematic dynamo action in a sheared helical flow at moderate to high values of the magnetic Reynolds number Rm. We find exponentially growing solutions which, for large enough shear, take the form of… read more here.
