Modulation of solar and stellar dynamos
SM Tobias - Astronomische Nachrichten, 2002 - Wiley Online Library
In this paper I will review the progress that has been made in understanding modulation of
solar and stellar dynamos. I will briefly discuss the observational evidence for modulation of …

The solar-cycle period-amplitude relation as evidence of hysteresis of the solar-cycle nonlinear magnetic oscillation and the long-term/55 year/cyclic modulation
H Yoshimura - Astrophysical Journal, Part 1, vol. 227, Feb. 1 …, 1979 - adsabs.harvard.edu
A new dynamical model of the solar cycle has predicted that the cycle should have a
hysteretic nature: the behavior of each 11 year cycle should depend on previous cycles. In …

The bimodal structure of the solar cycle
ZL Du - The Astrophysical Journal, 2015 - iopscience.iop.org
Some properties of the 11 yr solar cycle can be explained by the current solar dynamo
models. However, some other features remain not well understood such as the asymmetry of …

Correlation between decay rate and amplitude of solar cycles as revealed from observations and dynamo theory
Using different proxies of solar activity, we have studied the following features of the solar
cycle: i) The linear correlation between the amplitude of cycle and its decay rate, ii) the linear …

Solar activity in the past and the chaotic behaviour of the dynamo
R Arlt, N Weiss - The Solar Activity Cycle: Physical Causes and …, 2015 - Springer
The record of solar activity is reviewed here with emphasis on peculiarities. Since sunspot
positions tell us a lot more about the solar dynamo than the various global sunspot numbers …

No evidence for synchronization of the solar cycle by a “clock”
E Weisshaar, RH Cameron, M Schüssler - Astronomy & Astrophysics, 2023 - aanda.org
The length of the solar activity cycle fluctuates considerably. The temporal evolution of the
corresponding cycle phase, that is, the deviation of the epochs of activity minima or maxima …
