Stable Mass Transfer in Binaries Workshop - David Hendriks

Binary interactions shape the evolution, explosion, and afterlife of stars. The most common form of interaction is dynamically stable mass-transfer. The outcome of this mass-transfer phase is crucial to understanding the rate of most transient events (from stellar mergers, to stripped envelope supernovae and gravitational wave mergers), the kinematics of binary products (walkaway/runaways), and the formation rate of objects like Helium stars, white dwarfs, neutron stars and black holes.

Although much recent attention has been given to common envelope evolution, many uncertainties remain in the theoretical modeling of stable mass transfer, making predictions about this phase challenging from start to finish. Current models, whether in rapid binary population synthesis or detailed stellar structure codes, rely on simple analytic parameterization to address the aforementioned uncertainties.
