| Abstract: | Theoretical analysis and research for high-resolution photometric data of infrared continuum emission in BN object are made in this paper.Optically thin and spherical dust shell model is adopted,and physical parameters of the dust shell for BN object are derived.These parameters are as follows:dependences of optical thinkness and infrared continuum emissivity on wavelength,space distributions of dust density and temperature.The mass of the dust shell is also estimated. |
