Close encounters with the Death Star: Interactions between collapsed bodies and the Solar System

Popis výsledku v původním jazyce

We aim to investigate the consequences of a fast massive stellar remnant a black hole (BH) or a neutron star (NS) encountering a planetary system. We modelled a close encounter between the actual Solar System (SS) and a 2 M-circle dot NS and a 10 M-circle dot BH, using a few-body symplectic integrator. We used a range of impact parameters, orbital phases at the start of the simulation derived from the current SS orbital parameters, encounter velocities, and incidence angles relative to the plane of the SS. We give the distribution of possible outcomes, such as when the SS remains bound, when it suffers a partial or complete disruption, and in which cases the intruder is able to capture one or more planets, yielding planetary systems around a BH or a NS. We also show examples of the long-term stability of the captured planetary systems.
