Numerical simulations of interacting gas-rich barred galaxies: vertical impact of small companions.
BERENTZEN I., ATHANASSOULA E., HELLER C.H. and FRICKE K.J.
Abstract (from CDS):
The interactions produce expanding ring structures, offset bars, spokes and other asymmetries in the stars and gas. These characteristic signatures of the interaction are present in the disc for about 1 Gyr. We find that in some cases it is possible to destroy the bar while keeping the disc structure. In general, the central impacts cause larger damage to the bar and the disc than the peripheral ones. The interaction tends to accelerate the transition from a strongly-barred galaxy to a weakly- or non-barred galaxy. The final disc morphology is determined more by the impact position relative to the bar rather than the impact time.
