  In the late stage of terrestrial planet formation, planets are predicted to
undergo pairwise collisions known as giant impacts. Here we present a
high-resolution database of giant impacts for differentiated colliding bodies
of iron-silicate composition, with target masses ranging from 10^-4 M_Earth up
to super-Earths (5 M_Earth). We vary impactor-to-target mass ratio, core-mantle
(iron-silicate) fraction, impact velocity, and impact angle. Strength in the
form of friction is included in all simulations. We find that due to strength,
collisions with bodies smaller than about 2*10^-3 M_Earth can result in
irregular shapes, compound core structures, and captured binaries. We observe
that the characteristic escaping velocity of smaller remnants (debris) is
approximately half of the impact velocity, significantly faster than currently
assumed in N-body simulations of planet formation. Incorporating these results
in N-body planet formation studies would provide more realistic debris-debris
and debris-planet interactions.
