Grain Evolution in the Framework of Disk-Halo Interactions
Published online by Cambridge University Press: 03 August 2017
Abstract
The presence of dust grains at high galactic latitude as well as in the Halo of external galaxies has received substantial observative support in the last few years. Besides intense hydrodynamics stirring phenomena, like supernovae expanding shells, stellar winds and Galactic fountains, the removal of dust from the Disk can be ascribed to the global galactic radiation field. The continuous sputtering in the hot Halo gas may explain the large scale height found for refractory elements (Edgar and Savage, 1989).
