Observational Tests of Sgr A*'s State of the Accretion Flow
F. Yusef-Zadeh, R. G. Arendt, H. Bushouse +4
General relativistic magneto-hydrodynamic (GRMHD) simulations of the possibly magnetically arrested disk (MAD) of the accretion flow of Sgr A* predict short and long time variabili…

Second Generation Planet Formation in Post-AGB Discs: Testing the Role of Gravitational Instability
Ali Pourmand, Devika Kamath, Orsola De Marco +1
Post-asymptotic giant branch (post-AGB) binary stars are evolved systems that host circumbinary discs formed through mass loss during late stage binary interactions. Their structur…

Three-dimensional simulations of accretion disks in pre-CE systems
Ana L. Juarez-Garcia, Orsola De Marco, Fabio De Colle +4
Before a binary system enters into a common envelope (CE) phase, accretion from the primary star onto the companion star through Roche Lobe overflow (RLOF) will lead to the formati…
