Chemical Enrichment of the Halo by Dust Expulsion
The dynamical behaviour of dust grains subjected to light and matter distribution of spiral galaxies is analyzed in a hot galactic corona, including gas drag and sputtering. Grains can travel large radial and vertical distances from their original position removing material from the inner parts of the disk and sending it to the outskirts of the disk. Some heavy elements can be injected in the gas phase during the evolution in the galactic halos.
