Interpretation of standard photometric parameters of galaxies based on a two-component model.
Abstract
The analytic expressions for the standard photometric parameters of galaxies are obtained using the two-component model (bulge + exponential disk). The relative photometric structure of galaxies is shown to depend only on two non-dimensional parameters B/D and re/h. The theoretical values of the concentration indices for galaxies of different morphological types are calculated.
