Nbody simulations of instantaneous mass loss during dissipationless collapse
Abstract
The question as to whether instantaneous mass loss affects the remaining, relaxed bound system structure is addressed through Nbody collapse calculations, with and without mass loss. The calculations have determined that: (1) the amount of mass that can be lost while leaving an appreciable bound remnant is much larger than has been predicted by simple analytical models; and (2) within statistical uncertainties, the object remaining after mass loss possesses structural and dynamic characteristics that are virtually identical to those of a relaxed object that has collapsed without mass loss.
