Within the bounds of the general relativity and in gravidynamics, spherically-symmetric configurations are considered with the limit equation of state (P = (epsilon - 4B)/3) and with the density increasing to the center. It is shown that, unlike GR, where the existence of strange stars only is permissible (u-, d-, s-quarks), in the consistent dynamic theory of gravitation the existence of stable configuration with epsilon proportional to r exp -2 (quark star) is possible with a 'bag' out of quark-gluon plasma which includes all possible quark flavors (u, d, s, c, b, t, ...). The total mass of such a compact object with the bag of the radius about 10 km (whose surface consists of the strange self-bound matter) must be about 6-7 solar masses.
