Probing Infrared Sources By Computer Modeling

Abstract

The Infrared Astronomical Satellite (IRAS) has yielded a large and uniform sample of high quality data for various infrared sources. To interpret the IRAS observations, complementary theoretical studies have been undertaken which often involve modeling in detail the scattering, absorption, and emission of photons by dust grains. In the past decade, significant progress has been made at Rensselaer in the development of radiation transport models for infrared sources. Models with increasing degree of physical realism have been constructed. We review recent progress made in the modeling of infrared sources. Directions for future research in this area are briefly discussed.
