Evolution of interstellar dust.
Abstract
Observational evidence for the evolution of interstellar dust is reviewed. Important physical processes are identified. The problem of interstellar depletions is emphasized: with the best estimates for how rapidly grains are eroded, it is difficult to understand why elements such as Fe, Ca, and Si are so strongly depleted from the gas phase. Some other puzzles are mentioned.
