The dynamics of small-scale magnetic fields modulated by the solar cycle
M. Stangalini, G. Verth, V. Fedun +9
In addition to sunspots, which represent the most easily visualized manifestation of solar magnetism, cutting-edge observations of the solar atmosphere have uncovered a plethora of…
Shear-driven magnetic buoyancy in the solar tachocline: Dependence of the mean electromotive force on diffusivity and latitude
Craig D. Duguid, Paul J. Bushby, Toby S. Wood
The details of the dynamo process that is responsible for driving the solar magnetic activity cycle are still not fully understood. In particular, whilst differential rotation prov…
Shear-driven magnetic buoyancy in the solar tachocline: The mean electromotive force due to rotation
Craig D. Duguid, Paul J. Bushby, Toby S. Wood
The leading theoretical paradigm for the Sun's magnetic cycle is an -dynamo process, in which a combination of differential rotation and turbulent, helical flows produces a lar…
Estimating the rate of field line braiding in the solar corona by photospheric flows
Simon Candelaresi, David Pontin, Anthony Yeates +2
In this paper we seek to understand the timescale on which the photospheric motions on the Sun braid coronal magnetic field lines. This is a crucial ingredient for determining the…
Modulated cycles in an illustrative solar dynamo model with competing alpha effects
Laura Cole, Paul Bushby
The large-scale magnetic field in the Sun varies with a period of approximately 22 years, although the amplitude of the cycle is subject to long-term modulation with recurrent phas…
The coronal energy input from magnetic braiding
A. R. Yeates, F. Bianchi, B. T. Welsch +1
We estimate the energy input into the solar corona from photospheric footpoint motions, using observations of a plage region by the Hinode Solar Optical Telescope. Assuming a perfe…
