Modern models of interstellar dust

The new observational data on interstellar dust, obtained during the past few years, in particular, revised ISM elemental abundances, the polarization curve from the far UV to the near IR, spectra of dust infrared emission, extended red emission (ERE), are in serious conflict with existing dust models. We proposed here to use the regularization approach as a base for developing a modern dust model, which attempts to self-consistently explain most of the available observational data.
