Zásady pro vypracování

This thesis is focused on advancing the theory of binary star interactions. The immediate goal is to revisit the prescriptions for mass transfer in close binaries and investigate their influence on runaway phases of binary star evolution culminating in common envelope events. This evolutionary pathway is of great importance for producing many important astrophysical objects, including gravitational wave sources like binary black holes and double neutron stars. Depending on the interest of the student, this work will be extended and followed up with additional projects in single and binary star evolution or theoretical astrophysics in general. The tools of choice will be analytic and semi-analytic models, 1D stellar evolution calculations, numerical hydrodynamics potentially including radiation or magnetic fields, or N-body calculations. Participation in modeling of data, especially from the All-Sky Automated Survey for Supernovae, is possible.
