Two-dimensional model atmospheres of the Sun: influence of lateral boundary conditions.
Abstract
Influence of two kinds of lateral boundary conditions is studied in context of two-dimensional numerical modeling of solar granulation. The models with periodical conditions on lateral boundaries with respect to the similar models with reflecting sides demonstrate a) more essential contribution of large-scale inhomogeneous structures; b) larger amplitude of vertical oscillations near and above region of traditional temperature minimum. Parameters of primary mode of model oscillations do not depend on kind of lateral boundaries, however. Spectral calculations of 14 Fe I and 12 Fe II lines were additionally made as a test.
