Title: The dynamical evolution of disc-fragmented multiple systems
Abstract: The origin of very low-mass hydrogen-burning stars, brown dwarfs, and planetary-mass objects at the low-mass end of the initial mass function is not yet fully understood. Gravitational fragmentation of circumstellar discs provides a possible mechanism for the formation of such low-mass objects. The multiple systems formed through disc fragmentation are generally dynamical unstable, and I will introduce our computational study of the dynamical evolution of such systems. And this study can help to understand more about the origin of the low-mass objects.
