Probing Cosmic Infrared Sources: A Computer Modeling Approach
Abstract
The research in infrared astronomy has modeled several classes of infrared source sand modified and generalized existing computer codes. The effects of temperature fluctuations due to small grains on the energy spectrum and infrared surface brightness of interstellar clouds heated externally by the interstellar radiation field were studied. A detailed study has begun on the grain formation problem in stellar outflows. The effects of fractal dust grains on the spectrum of infrared sources has been studied. Models are being developed of the physical conditions in the circumstellar envelopes of evolved stars. The chemistry of two dense inter-stellar clouds is being studied. The effect of temperature dependent opacity on the emergent spectra of infrared sources is being investigated.
