Predicting Solar Sigmoid Lifetimes Based on Shearing in the Photosphere [PDF]
, 2015 This project’s purpose was to study how the speed at which the plasma in the photosphere of the sun affects the lifetime and shape of a solar sigmoid. Solar sigmoids are S-shaped, twisted magnetic structures that are due to the shifting magnetic field ...

Inferring Photospheric Horizontal Flows from Multiple Observations with SUVEL Models
The Astrophysical JournalPhotospheric horizontal velocity fields play essential roles in the formation and evolution of numerous solar activities. Various methods for estimating the horizontal velocity field have been proposed in the past.

Transport of Solar Wind Fluctuations: A Two-Component Model [PDF]
, 2011 We present a new model for the transport of solar wind fluctuations which treats them as two interacting incompressible components: quasi-two-dimensional turbulence and a wave-like piece.

Refinements to the Solar Polar Magnetic Flux: Implications from Inversion Methodologies
The Astrophysical JournalThe magnetic fields in the solar polar region are important to our understanding of the internal dynamo process, the global coronal structure, and the origin of the solar wind.

Magnetohydrodynamic code for gravitationally-stratified media [PDF]
, 2008 Aims. We describe a newly-developed magnetohydrodynamic (MHD) code with the capacity to simulate the interaction of any arbitrary perturbation (i.e., not necessarily limited to the linearised limit) with a magnetohydrostatic equilibrium background ...

Observational Evidence of Shallow Origins for the Magnetic Fields of Solar Cycles
Frontiers in Astronomy and Space Sciences, 2018 Observational evidence for the origin of active region magnetic fields has been sought from published information on extended solar cycles, statistical distributions of active regions and ephemeral regions, helioseismology results, positional ...
