Abstract (from CDS):

This observational study is about the effects of interaction on the kinematics and chemical abundance of the component galaxies of AM 2229-735. This system is formed by a disc galaxy, NED01, and a compact perturbed Sb(s)-like galaxy, NED02, the latter showing a tail and counter-tail arc-shaped feature. This system could be a progenitor of a polar ring galaxy. The sky-projected tail is very luminous and seems to connect the galaxies. Our study was based on BVRI broad-band imagery as well as long-slit spectroscopy in the wavelength range 4240-8700 Å. We estimated heliocentric radial velocities of 17 518±25 km/s (NED01) and 17 326±27 km/s (NED02). Standard diagnostic diagrams were used to classify the main ionizing source of selected emission-line regions. It turns out that all regions are mainly ionized by massive stars. Using two empirical methods, we found that the H ii regions in AM 2229-735 have high metallicity: 12 + log(O/H) = 8.3-8.6 dex.
