Abstract

Single versus binary star evolution

Pablo Marchant (CIERA, Northwestern University)

In the past years it has been established that most massive stars will strongly interact with a binary companion, significantly altering their subsequent evolution. Understanding stellar populations then requires extensive modeling of both single and binary stars, but significant uncertainties remain in our theoretical models. Moreover, recent developments such as the detection of merging binary black holes by the aLIGO observatory and multiple results from transient surveys further increase the need for accurate models in order to understand the astrophysical implications of these observations. In this talk I will review some of the biggest pending questions and recent advances in the the theory of single and binary stellar evolution, including mass loss, mixing, the generation of magnetic fields, the efficiency of mass transfer and common envelope evolution.
