Perturbation of the accretion flow onto supermassive black hole by a passing star

The close neighbourhood of a supermassive black hole contains not only the accreting gas and dust but also stellar-sized objects like stars, stellar-mass black holes, neutron stars, dust-enshrouded objects, etc. These entities interact with the accreting medium and perturb the quasi-stationary configuration of the accretion flow. We investigate how the passage of a star can influence the black hole environment with GRMHD 2D and 3D simulations. We focus on the changes in the accretion rate as well as the emergence of outflowing blobs of plasma.
