  We extend previous real-space Hartree-Fock studies of static stripe stability
to determine the phase diagram of the Hubbard model with anisotropic
nearest-neighbor hopping t, by varying the on-site Coulomb repulsion U and
investigating locally stable structures for representative hole doping levels
x=1/8 and x=1/6. We also report the changes in stability of these stripes in
the extended Hubbard model due to next-neighbor hopping t' and to a
nearest-neighbor Coulomb interaction V.
