Ion irradiation of asphaltite as an analogue for solid hydrocarbons in the interstellar medium

, 2005
We present the results of experiments of low temperature ion irradiation of pure asphaltite samples and those covered with water ice layers. Asphaltite (a natural bitumen) was used as an analogue of carbonaceous interstellar grains on which water-rich ...
