A powerful, new computer model provides fresh insight into the turbulent death throes of supernovae (see Section 13.2, p. 337).

The new model, developed by W. David Arnett (U. of Arizona) and colleagues, is the first to represent the start of a supernova collapse in three dimensions. It shows how the turbulent mixing of elements inside stars causes them to expand, contract, and spit out matter before they finally detonate. Arnett’s new model better matches what we observe in supernova remnants, with ejections of star material mixing with the material expelled during its final explosion.

The article, ‘Chaos and turbulent nucleosynthesis prior to a supernova explosion’ by David Arnett, Casey Meakin and Maxime Viallet is published in the journal AIP Advances.
