Title: It Takes Two to Tango: How Binary Stars Evolve into Gravitational Wave Sources
Abstract: With the discovery of dozens of merging black holes and neutron stars by gravitational wave observatories over the past four years, the study of the complexities of binary star evolution physics - including mass transfer, tides, and r-process nucleosynthesis - has taken on a new urgency. In this talk, I will describe the current status of binary evolution models as well as several critical shortcomings and how my collaborators and I, along with the rest of the field, are systematically addressing these. I will focus on both improvements to physical processes, such as the common envelope in which a neutron star or black hole becomes engulfed within a giant star’s envelope, as well as the introduction of modern statistical and machine learning methods using dedicated supercomputers. |
