Stationary spherically-symmetric distributions of a self-gravitating nonlinear spinor field with nonlinearity of the type \( {\left(\overline{\Psi}\Psi \right)}^n \) are considered within the framework of Einstein’s theory of gravitation. Possible astrophysical effects of such material distributions are investigated; in particular, it is shown that for n = 2 a nonlinear spinor field of Ivanenko–Heisenberg type corresponds to the possible formation of wormholes with a flat asymptotic.
