On the connections between solar and stellar dynamo models

, 2016
We here discuss the various dynamo models which have been designed to explain the generation and evolution of large-scale magnetic fields in stars. We focus on the models that have been applied to the Sun and can be tested for other solar-type stars now ...

Dynamo of the Sun and Solar-Type Stars

, 2009
The objective of this paper is to give a review of solar and stellar activity, from the observationnal constraints to dynamo models. I first review solar observations and insist on the various scales. Then I describe the photospheric magnetic structures (

The Dependence of Joy’s Law and Mean Tilt as a Function of Flux Emergence Phase

The Astrophysical Journal
Data from the Michelson Doppler Imager (MDI) and Helioseismic and Magnetic Imager (HMI) are analyzed from 1996 to 2023 to investigate tilt angles ( γ ) of bipolar magnetic regions and Joy’s law for Solar Cycles 23 and 24 and a portion of Cycle 25.

Solar Cycle 24 and the Solar Dynamo

, 2007
We will discuss the polar field precursor method for solar activity prediction, which predicts cycle 24 will be significantly lower than recent activity cycles, and some new ideas rejuvenating Babcock's shallow surface dynamo.

Locating the seat of the solar dynamo

, 1989
The hypothesis that the solar dynamo operates in a thin layer at the bottom of the convection zone is addressed. Recent work on the question whether the magnetic flux can be made to emerge at sunspot latitudes is reviewed.
