Lay Summary (English)

Lead
Lay summary
This project is an 'Indivudual Project' (IP) part of a Collaborative Research Project submitted in the frame of the EuroGENESIS programme from the ESF. This IP aims at studying the mixing of elements in core-collapse supernova explosion and ejecta and its impact on the formation process, chemical composition and mass yields of dust. The explosion mechanism, the nucleosynthesis and mixing, and the chemistry have traditionally been investigated separately. New insight can be obtained if mutually connected phases are coupled, especially in deriving the exact amount of dust formed in supernovae and its chemical nature. Once the interplay between the mixing resulting from the explosion and the dust formation mechanism are well characterised, the time evolution and reprocessing of dust in young supernova remnants will be studied. In particular, the impact of the reverse shock on the ejecta material will be investigated to assess the chemistry at play in supernova remnants.
