Solar Granulation : Overview

  • R. Muller
Part of the NATO ASI Series book series (ASIC, volume 263)

Abstract

During the last few years the solar granulation has been extensively investigated thanks to new high quality material, and to the development of sophisticated and powerful image processing techniques. The material consists of distorsion-free granulation movies performed with the SOUP experiment on board of Spacelab-2 and of high resolution ground-based pictures and spectra. In this review paper emphazis is put on those properties which can help us to understand better the origin of the granulation. In particular several results favour a turbulent origin : the size histogram, the fractal dimension, the kinetic energy power spectrum, the fragmentation which appears to be the main process of disappearance. The mesogranulation is revealed by surface granular flows as well as by the spatial distribution of particular granules. The granular pattern is perturbed by the presence of magnetic fields, but in various ways depending on the situation. It undergoes variations over the solar cycle.
