摘要
The role of radial migration on the chemical evolution of the Milky Way is studied with semi-analytical models of disk evolution, using several new/updated ingredients and parametrized prescriptions for blurring and churning. It is found that radial migration impacts on several properties of the local disk (shape and dispersion of the age-metallicity relation, metallicity distribution), it may explain some chemical properties of the local thin and thick disks (i.e. the two-branch shape of the O/Fe vs. Fe/H relation) and it affects the past abundance profiles of the stellar population.
