Explore stellar mass binaries in active galactic nuclei (AGN) through this 48-minute conference talk by Hui Li and Barry McKernan at the Kavli Institute for Theoretical Physics. Delve into the evolution and influence of circumbinary gas on binary systems, from stars to supermassive black holes in galactic nuclei. Examine observational signatures, numerical modeling techniques, and the similarities between massive black hole binaries and stellar binaries. Learn about recent progress in observations and modeling, and discover crucial next steps in advancing our understanding of these systems. Cover topics such as formation, rate prediction, numerical experiments, star formation, and hyperEddington accretion. Gain insights into the role of radiation, supernova explosions, and potential signatures in AGN environments.
