Yale University. Conclusions. Compact objects such as stars and black holes generally form in larger systems such as binaries, multiple systems, star clusters, or galaxies.. Gravitational interactions in these larger systems play a major role in the formation of compact objects by transporting angular momentum.. Will M. Farr. Northwestern University, CIERA. (See .
