  Numerical investigation of the static spherically symmetric vacuum solution
of the Logunov equations confirms the analytical results and demonstrates a
strong repulsion at sub-Planckian distance from the Schwarzschild-like
singularity, which is stable against the small perturbations. We suppose that
the final stage of the stellar collapse in the relativistic theory of
gravitation can entail the gravitational bursts with the gravitons
overproduction due to the strong deceleration in the vicinity of the
Schwarzschild sphere. The rigorous investigation of this topic requires a
quantum-field consideration.
