A scaling law of interstellar depletions as a tool for abundance studies of Damped Ly alpha systems
arXiv:astro-ph/0110499
Abstract
An analytical expression is presented that allows dust depletions to be estimated in different types of interstellar environments, including Damped Ly alpha systems. The expression is a scaling law of a reference depletion pattern and takes into account the possibility that the dust chemical composition may vary as a function of the dust-to-metals ratio and of the intrinsic abundances of the medium. Preliminary tests and applications of the proposed scaling law are briefly reported.
