Hadronic effective field theories describing ordinary nuclei also contain Q-Ball solutions which can describe a new state of matter, “baryon matter”. Baryon matter is stable in very small chunks as well as in stellar-sized objects, since it is held together by the strong force instead of just gravity. Larger chunks, “Q-Stars”, in which gravity is important, model neutron stars. A wide variety of Q-Star models, all consistent with known nuclear physics, allow compact objects to have masses much larger, or rotation periods much shorter, than is conventionally believed possible. Smaller chunks of nuclear density baryon matter could also be astrophysically important components of the universe, and at late times would have many properties similar to those of strange matter chunks.
