We prove that the stabilizer of an attractive fixed point in ∂FN of an irreducible with irreducible powers automorphism of a free group FN is virtually cyclic. The proof uses the attractive lamination of such an automorphism. We also establish the complete list of all possible maximal subgroups of Aut(F2) which fix a point of the boundary ∂F2.
