... By undertaking a spectral and photometric investiґ gation of the central part of the bright elliptical galaxy NGC 759, we have found an optical counterpart for the circumnuclear molecular gas ring with the radius of # 3 ## (# 1 kpc) which was earlier reported by Wiklind et al. ... 2 Fig. ... More likely, this ring may be a consequence of a tidal encounter between the elliptical galaxy NGC 759 and a large spiral galaxy which was accompanied by a substantial gas accretion. ...
