Vorticity in the solar photosphere [PDF]

, 2010
Aims. We use magnetic and non-magnetic 3D numerical simulations of solar granulation and G-band radiative diagnostics from the resulting models to analyse the generation of small-scale vortex motions in the solar photosphere.Methods.

Solar Surface Convection

Living Reviews in Solar Physics, 2009
We review the properties of solar convection that are directly observable at the solar surface, and discuss the relevant underlying physics, concentrating mostly on a range of depths from the temperature minimum down to about 20 Mm below the visible ...

Observational Evidence of Vortex-driven Information Transfer in the Solar Atmosphere: Insights from Sunrise iii

The Astrophysical Journal Letters
Using high-resolution observations from the TuMag instrument aboard the Sunrise iii solar observatory balloon mission, we investigate solar vortices in the lower atmosphere.

Accuracy Analysis for Shack–Hartmann Wave Front Sensing with Extended Sources

The Astrophysical Journal
Correlating the Shack–Hartmann wave front sensor (SH-WFS) with extended targets is widely used in solar adaptive optics systems. This paper aims to introduce a theoretical analysis that evaluates the accuracy of the SH-WFS on extended sources, with a ...

Modeling Solar Oscillation Power Spectra. III. Spatiotemporal Spectra of Solar Granulation Velocity Field as Seen in HMI Velocity Measurements

The Astrophysical Journal
We suggest a physically motivated model of the uncorrelated background, which can be used to improve the accuracy of helioseismic frequency measurements when the background contributes significantly to the formation of spectral lines of acoustic ...

Data-driven Radiative Hydrodynamics Simulations of the Solar Photosphere Using Physics-informed Neural Networks: Proof of Concept

The Astrophysical Journal
Current, realistic numerical simulations of the solar atmosphere reproduce observations in a statistical sense; they do not replicate observations such as a movie of solar granulation.

Morphological variations of solar granules in the presence of magnetic fields

Astronomy & Astrophysics
Context. Solar granulation consists of dynamic convective plasma cells that rise from the solar interior to the surface. The interaction between this plasma cells and the Sun’s magnetic field provides valuable insights into the dynamics of plasma near ...
