Nuclear Neural Networks: Emulating Late Burning Stages in Core Collapse Supernova Progenitors

Aldana Grichener, Mathieu Renzo, Wolfgang E. Kerzendorf +7

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…

Circumbinary disks in post common envelope binary systems with compact objects

Lotem Unger, Aldana Grichener, Noam Soker

We conduct a population synthesis study using the binary population synthesis code compas to explore the formation of circumbinary disks (CBDs) following the common envelope evolut…
