Nuclear Neural Networks: Emulating Late Burning Stages in Core-collapse Supernova Progenitors Open
One of the main challenges in modeling massive stars to the onset of core collapse is the computational bottleneck of nucleosynthesis during advanced burning stages. The number of isotopes formed requires solving a large set of fully coupl…

Carbon from massive binary-stripped stars over cosmic time: effect of metallicity Open
The origin of carbon in the Universe remains uncertain. At solar metallicity, binary-stripped massive stars -- stars that lost their envelope through stable interaction with a companion -- have been suggested to produce twice as much carbo…
