Abstract
- We present the results of photometric and spectroscopic observations of UGC 4892—a candidate for polar-ring galaxies. We show that the feature in the brightness distribution described by Whitmore et al. (1990) as a possible polar ring is actually a companion galaxy that interacts with the giant main galaxy. The velocity fields of the gas and stellar components can be explained by assuming that the gas lost by the companion galaxy and captured by the main galaxy forms a gaseous stream rotating around the latter in a plane almost perpendicular to its principal plane.
