MORPHOLOGICAL-STUDY OF THE SOLAR GRANULATION .1. DARK DOT FORMATION IN THE CELL

High resolution images of the solar granulation show the presence of the small dot-like dark regions in the granulation cells. From the study of the characteristics of these dark regions, it is found that the dark regions are formed without any relations to the presence of the magnetic field. Moreover, it is observed that a granulation cell splits in a few minutes after the formation of the dark regions in the cell. Similarities and differences between the granules with the dark regions and the so-called exploding granules are discussed. © 1979 D. Reidel Publishing Co.
