POSYDON: A General-Purpose Population Synthesis Code with Detailed Binary-Evolution Simulations

Understand

Most massive stars are members of a binary or a higher-order stellar systems, where the presence of a binary companion can decisively alter their evolution via binary interactions.

• Interacting binaries are also important astrophysical laboratories for the study of compact objects.
• Binary population synthesis studies have been used extensively over the last two decades to interpret observations of compact-object binaries and to decipher the physical processes that lead to their formation.
• Here, we present POSYDON, a novel, binary population synthesis code that incorporates full stellar-structure and binary-evolution modeling, using the MESA code, throughout the whole evolution of the binaries.
