Theoretical Microbial Model For Small Magellanic Cloud Extinction Curve

Abstract

It was found that interstellar extinction observational data for Small Magellanic Cloud, were in a good agreement with a laboratory spectra for bacteria in ultraviolet region ,which gives the priority for microorganisms (dry) to explain the behavior of interstellar extinction in this region. The importance of this study rises from the fact that extinction of starlight provides close to the mechanisms of formation and destruction of grains size, shape and composition of the grains are manifested in the characteristic of the extinction produced
