Structural features of sun photosphere under high spatial resolution
Abstract
The main small-scale elements observed in the solar photosphere at high resolution are discussed: granules, faculaes, micropores. As a separate element of the fine structure, a continuous network of dark intergranular gaps is considered. The results of image processing of micropores and faculaes knots obtained using modern adaptive telescopes are presented. For intergranular gaps and micropores, a stationary regime of magnetic diffusion is determined, in which horizontal-vertical plasma flows converging to the gap (and micropores) compensate for the dissipative spreading of the magnetic flux on a given scale. A theoretical assessment of the characteristic scales of these structures in the photosphere is obtained: 20-30 km for the thickness of dark intergranular spaces and 200-400 km for the diameter of micropores.
