Detailed studies and modeling of the peculiar galaxy UGC 10205 (VV 624)

The results of detailed photometric studies of the peculiar galaxy UGV 1020 5 are presented. The observed surface-brightness distribution and rotation curve are investigated in the framework of a two-component model with a bul ge acid disk. The overall photometric and kinematic characteristics are con sistent with those of a normal giant early-type (S0/aSa) galaxy. The main p eculiarities of the galaxy (the presence of a weak asymmetric envelope and strongly noncircular gas motions in the nuclear region) are explained using a numerical model in which an early stage is observed in the capture and t idal disruption of a small type E/S0 companion by the massive central galax y.
