Description

I will present the results of simulations comparing accretion onto a low-mass black hole with accretion onto a neutron star of the same mass. Even when both are initialized with the same conditions, the simulations for the black hole are significantly different from those for the neutron star. In the case of the black hole, the accretion disk becomes magnetically arrested, resulting in lower luminosity.
The result is: Black holes do not eat and they get MAD if you force them to.
