Explore circumbinary disks across different scales in this 47-minute conference talk by Roman Rafikov at the Kavli Institute for Theoretical Physics. Delve into the evolution and influence of circumbinary gas on binary systems, from stellar binaries to supermassive black holes in galactic nuclei. Examine observational signatures, numerical modeling techniques, and the similarities between problems at varied astrophysical scales. Cover topics including GW Orionis, GG Tauri, HD 98800, gas dynamics around binaries, circuit binary disks, historical perspectives, binary torque decay, and orbital evolution. Gain insights from this presentation, part of the "Building Bridges: Towards a Unified Picture of Stellar and Black Hole Binary Accretion and Evolution" conference, which brings together experts in massive black hole binaries and stellar binaries to advance understanding in this field.
