The metallic winds in dwarf galaxies
  We present results from models of galactic winds driven by energy injected
from nuclear (at the galactic center) and non-nuclear starbursts. The total
energy of the starburst is provided by very massive young stellar
clusters,which can push the galactic interstellar medium and produce an
important outflow. Such outflow can be a well, or partially mixed wind, or a
highly metallic wind. We have performed adiabatic 3D N-Body/Smooth Particle
Hydrodynamics simulations of galactic winds using the GADGET-2 code. The
numerical models cover a wide range of parameters, varying the galaxy
concentration index, gas fraction of the galactic disk, and radial distance of
the starburst. We show that an off-center starburst in dwarf galaxies is the
most effective mechanism to produce a significant loss of metals (material from
the starburst itself). At the same time a non-nuclear starburst produce a high
efficiency of metal loss, in spite of having a moderate to low mass loss rate.
