A theoretical analysis is presented of the problem of nuclear matter under intensive pion condensation. The equation of state in the problem is calculated for several sets of nuclear constants such that a nuclear plasma can form in a bounded system. The equation is used to simulate the physical characteristics of celestial bodies which exist even when self-gravitation is not present. Some notable features of the simulated systems include: a nuclear matter configuration of arbitrarily low-mass; a supernuclear density which decreases abruptly to zero at the surface; and an increase in density toward the center no greater than a factor of 4. The mass, radius, relativistic moment of inertia, and binding energy of the systems are evaluated as functions of the central density. It is shown that a stable configuration with the above properties will have a mass no greter than about 1.16 solar mass.
