Genesis and evolution of dust in galaxies in the early Universe I. Modeling dust evolution in starburst galaxies

Understand

We have developed a numerical galactic chemical evolution model.

• The model is constructed such that the effect of a wide range of parameters can be investigated.
• It takes into account results from stellar evolution models, a differentiation between diverse types of core collapse SNe and the contribution of AGB stars in the mass range 3-8 Msun.
• We consider the lifetime-dependent yield injection into the ISM by all sources as well as dust destruction due to SN shocks in the ISM.
