Artificial granules in 2-D solar models

  • A. S. Gadun

Two-dimensional, hydrodynamic, time-dependent models of solar granulation have been used to determine characteristics of artificial granules. It is found that the evolution of granules which subsequently fragment, respectively disappear, is fundamentally different. Dissolution of artificial granules is the basic process (48%–58%) in 2-D models. The number of small-scale and short-lived granules increases continuously toward the smaller scales. The main contributor to the total area are the granules with sizes about ∼900–1000 km. The mean lifetime of artificial granules is estimated to be 6–11 min.
