Abstract

Carbon nanoparticles, prepared by means of ns-laser ablation of carbon can be used for physical modeling of the interstellar dust. Different model for formation of interstellar dust were suggested for the last years, one assumes that carbon grains are generated by condensation in the expanding carbon-rich stellar plasma/vapor of cool red giants. Similar conditions for condensation can be reproduced in laser experiments. Calculations and experiments show that carbon particles produced by laser have the same size and extinction that can be seen in diffusive clouds of hydrogen-pure stars. The situation with hydrogen-rich stars is more complex: the most probable mechanism suggests that firstly the nanodiamonds are formed within these clouds which later transform to carbon onions due to annealing and graphitization.
