Abstract
We show that certain classical solutions of hadronic effective field theories can model neutron stars. Within the uncertainties of what is known from laboratory measurements of nuclear physics, these solutions, called Q-stars, may have masses much larger (>> 3 M solar) or may be able to rotate faster (Prot < 0.5 ms) than previously believed possible. Stable chunks of nuclear density baryonic matter varying in size from 10-12 cm to several kilometers may also exist. Cygnus X-1, LMC X-3, and the SN1987A remnant are candidates for Q-stars.
