Abstract

Various small scale photospheric processes are responsible for spatial and temporal variations of solar emer- gent intensity. The contribution to total irradiance fluctua- tions of such small scale features is the solar irradiance back- ground. Here we examine the statistical properties of irradi- ance background computed via a n-body numerical scheme mimicking photospheric space-time correlations and cal- ibrated by means of IBIS/DST spectro-polarimetric data. Such computed properties are compared with experimen- tal results derived from the analysis of a VIRGO/SPM data. A future application of the model here presented could be the interpretation of stellar irradiance power spectra ob- served by new missions such as Kepler.
