Scientific paper

Oort cometary cloud models having different cometary body concentration distributions are constructed under the assumption that the sun penetrates a binary system with a low-mass companion. Spherical and nonspherical luminosity components as well as the thermal emission spectra of the dense inner core are calculated using various models with the total mass equal to 100 solar masses. Depending on the model used, the far infrared radiation spectra are characterized by maxima at wavelengths of 1 mm to 100 microns, concentrated in the 300-micron region in the case of black bodies, and in the 100-micron region in the case of ice. It is shown that the radiation can have specific large-scale anisotropy due to the solar companion.
