  We are interested on the effects, caused by strong variable density dependent
magnetic fields, on hyperonic matter, its symmetry energy, equations of state
and mass-radius relations. The inclusion of the anomalous magnetic moment of
the particles involved in a stellar system is performed, and some results are
compared with the cases that do not take this correction under consideration.
The Lagrangian density used follows the nonlinear Walecka model plus the
leptons subjected to an external magnetic field.
