Detailed Structure and Evolution Modeling of the Tightest Massive Binary Stars

In this PhD thesis, Matthias Fabry takes a deep dive into the detailed structure and evolution of the most massive and tightest binary stars. Massive stars are predominantly born in binary systems, and recent modeling shows that about 40% of them will form a so-called contact binary during their life. In this configuration, both stars share their outer layers, forming peanut-shaped objects. Previo...
