Query: Chemo-dynamical evolution of tidal dwarf galaxies. II. The long-term
  evolution and influence of a tidal field   In a series of papers, we present detailed chemo-dynamical simulations of
tidal dwarf galaxies (TDGs). After the first paper, where we focused on the
very early evolution, we present in this work simulations on the long-term
evolution of TDGs, ranging from their formation to an age of 3 Gyr. Dark-matter
free TDGs may constitute a significant component of the dwarf galaxy (DG)
population. But it remains to be demonstrated that TDGs can survive their
formation phase given stellar feedback processes, the time-variable tidal field
of the post-encounter host galaxy and its dark matter halo and ram-pressure
wind from the gaseous halo of the host. For robust results the maximally
damaging feedback by a fully populated invariant stellar IMF in each star
cluster is assumed, such that fractions of massive stars contribute during
phases of low star-formation rates. The model galaxies are studied in terms of
their star-formation history, chemical enrichment and rotational curves. All
models evolve into a self-regulated long-term equilibrium star-formation phase
lasting for the full simulation time, whereby the TDGs become significantly
more compact and sustain significantly higher SFRs through compressive tides
than the isolated model. None of the models is disrupted despite the unphysical
extreme feedback, and none of the rotation curves achieves the high values
observed in real TDGs, despite non-virial gas accretion phases.
