A possible relation between lifetime and location of solar granules
Abstract
The authors have studied the spatial distribution of the long-lived granules from a population of 346 granules located in a photospheric region 37arcsec×37arcsec. The study is based on an exceptional sequence of pictures taken at the Pic-du-Midi Observatory on May 16, 1979. The authors consider as long-lived granules all the granules with lifetime greater than the mean lifetime of the population (≈15 min). They have found that they are not randomly distributed, but they are located in cellular regions that cover ≈35% of the whole area of the region under study. The possible relation of the pattern composed by the long-lived granules with the "mesogranulation" is discussed.
