Explore accretion processes within circumplanetary disks and their similarities to black hole mini-disks in this 29-minute conference talk by Judit Szulagyi from ETH Zurich. Delve into dust-included simulations, examining the roles of opacity, shocks, gravitational potential, and viscosity in shaping these systems. Investigate gap profiles, three-dimensionality, and observational predictions for both planetary and black hole disks. Gain insights from planet formation studies and their applications to broader astrophysical contexts, including migration patterns and imaging techniques. Part of the "Building Bridges" conference at the Kavli Institute for Theoretical Physics, this talk bridges stellar and black hole binary accretion research, offering a unified perspective on these diverse astrophysical phenomena.
