The hypothesis that strange quark matter is the true ground state of matter has been investigated for almost four decades, but only a few works have explored the dynamics of binary systems of quark stars.

By simulating the merger of black hole--neutron star systems of exactly the same masses and spins, we show that these fast ejecta are entirely absent, if the primary is instead a black hole.

Hence, the measurement of these corrections has the potential of providing important information on the equation of state of nuclear matter.

We find that the absence of an event horizon in a boson star leads to important differences in the dynamics of the accretion and results in both the formation of a small torus in the interior of the boson star and in the absence of an evacuated high-magnetization funnel in the polar regions.

Our Galactic Center, Sagittarius A* (Sgr A*), is believed to harbour a supermassive black hole (BH), as suggested by observations tracking individual orbiting stars.
