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.

Hemispheric Asymmetry of Solar Active Regions Arises from a Nested Population

The Astrophysical Journal Letters
We investigate the longitude–time distribution of NOAA active regions (ARs) during Solar Cycles 22–24 and find statistically significant north–south asymmetry in AR emergence.

An elementary introduction to solar dynamo theory

, 2007
The cyclically varying magnetic field of the Sun is believed to be produced by the hydromagnetic dynamo process. We first summarize the relevant observational data pertaining to sunspots and solar cycle.

Stochastic fluctuations of the solar dynamo

, 1992
Attempts in the past to model the irregularities of the solar cycle (such as the Maunder minimum) were based on studies of the nonlinear feedback of magnetic fields on the dynamo source terms. Since the alpha-coefficient is obtained by averaging over the
