Zakhozhay O. Spectral energy distribution peculiarities of systems with circumsubstellar disks.

The dissertation is devoted to the development of existed methods and creation of new algorithm for spectral energy distributions of systems with circumsubstellar protoplanetary disks. New algorithm takes into account age, geometrical and physical systems characteristics. The formulas that permit at first to calculate limiting angles for systems inclination and then areas of emitting surfaces for systems that contain spherical central source and surrounded disk have being received. Using these formulas 1120 spectral energy distributions for substars with disks that have different geometry and inclination angle are calculated. Calculated arrays for irradiated fluxes that have being calculated with new algorithm are analyzed. Regularities between substellar physical parameters, protoplanetary disk geometrical characteristics and their total fluxes are determined. Limited fluxes for systems irradiation as a dependence of substellar masses and ages, disk geometrical parameters (inner and outer radii, height changing law) and inclination toward observer are received. Developed calculations algorithm and received models are approved on fluxes that were received with ground-based and space observations. New disks characteristics for 10 substars from Upper Scorpius open cluster are determined.
