Explore a conference talk on simulating accretion in the inner cavity of circumbinary disks, presented by Philipp Moesta from the University of Amsterdam. Delve into the complexities of binary systems, from stars to supermassive black holes, and their interactions with surrounding circumbinary gas. Learn about the evolution of this gas, its influence on embedded binaries, and the observational signatures that provide valuable insights. Discover the novel numerical techniques required to model these systems effectively. Gain perspective on the similarities between massive black hole binaries and stellar binaries, and understand the importance of bringing together these two distinct research communities. Examine topics such as project setup, modelling eccentricity, orbital evolution, internal cavity characteristics, potential shock emission, and microphysics. Engage with the latest advancements in observations of stellar binaries and numerical modeling of both stars and black holes, while considering the crucial next steps in expanding our knowledge of these fascinating astrophysical phenomena.
