Photoprocessing-driven dust evolution in the diffuse ISM
Abstract
Results from the latest generation of surveys in the microwave and submillimeter domain (Planck, Herschel) suggest that the optical properties of dust in the diffuse interstellar medium are not fixed, but change from region to region, possibly due to dust evolution. Interstellar dust models need to explain this variability. The hydrogenated amorphous carbons collectively known as aC(:H) are very interesting candidate dust components in this respect: their optical properties can be modified by ultraviolet photoprocessing, so that the dust properties will vary with the environmental conditions and previous dust history. We are currently working on a model containing a-C(:H) to determine what physical parameters can reproduce the variations of dust emission observed by Planck. We show here the effects of varying the amount of a-C(:H) photoprocessing and of carbon accretion from the gas phase....
