Watch this 16-minute conference talk exploring how triple star systems influence the evolution and characteristics of accreting binary populations. Examine the complex dynamics that occur when a third stellar companion interacts with binary systems containing black holes or neutron stars, and discover how these interactions affect mass transfer rates, orbital evolution, and the eventual detectability of these systems through gravitational waves. Learn about the theoretical frameworks used to model triple system evolution and understand how hierarchical configurations can drive binaries toward closer orbits through mechanisms like Kozai-Lidov oscillations. Explore observational evidence for triple-induced evolution in accreting binaries and consider the implications for population synthesis models that aim to predict the rates and properties of compact object mergers. Gain insights into how accounting for triple star interactions may help explain observed discrepancies between theoretical predictions and gravitational wave detection rates, while also understanding the role these systems play in the broader context of stellar black hole lifecycles from formation through potential merger events.
