Abstract

Most massive stars are found in hierarchical triples or higher multiplicity systems in which a close inner binary is orbited by one or more distant companions (Moe & Di Stefano, 2017). A distant companion may significantly alter the evolution of the system by causing large-amplitude oscillations of the inner binary eccentricity (so-called von Zeipel-Kozai-Lidov oscillations; Naoz, 2016). These oscillations determine how close the inner binary stars pass each other at periapsis and are therefore essential for our understanding of interactions between massive binary stars (Sana et al., 2012) as well as their compact remnants. Understanding the role of tertiary companions for the evolution of massive stars requires an efficient numerical tool to simulate the complex interplay between the dynamics of hierarchical triples and their stellar evolution.
