Bar Formation in Interacting Galaxies and the Fueling of Nuclei

  • M. Noguchi


Recent observations suggest that interacting galaxies show a statistically higher incidence of nuclear starbursts than isolated galaxies (e.g., Keel et al. 1985). This means that the nuclear region of an interacting galaxy is somehow fuelled with the gas. Here the following mechanism for the gas fuelling is proposed based on the results of numerical simulations. Namely, the tidal force of the companion galaxy induces a bar structure in the stellar disc component of the perturbed galaxy (the parent galaxy), and this bar in turn induces infall of interstellar gas to the central disc region. Full description is given in Noguchi (1987, 1988).
