Central regions of the polar-ring galaxies NGC 2685 and IC 1689.

SIL'CHENKO O.K.

Abstract (from CDS):

Result. of two-dimensional spectroscopy for central parts of polar-ring galaxies NGC 2685 and IC 1689 are presented. An orthogonality of star and gas rotations is detected. A strong break of absorption-line index Mgb between the nuclei and the inner bulges ("chemically decoupled nuclei") and perhaps an intermediate age of the stellar population in the nucleus of IC 1689 imply secondary star formation bursts in the centers of the polar-ring galaxies which are possibly related to accretion events having produced polar rings themselves.
