Notes on Structures in NGC 7176
NGC 7173 and NGC 7176 - both galaxies
belong to the compact group Hickson 90. Detailed kinematical and
photometric studies
(Longo et al. 1994b;
Longo et al. 1995) show that NGC 7173
is undergoing a phase of strong interaction with the late-type galaxy
NGC 7174.
These three galaxies form a subgroup which is very likely to be
interacting with the fourth member of the group,
NGC 7172.
Both galaxies present very small inner disks in the
Laplacian image.
In NGC 7176 we find what looks like a tiny stellar
disk (r = 2.5", PA = 55°). The
intricate pattern of features dominating the lower part of the image is the
late-type galaxy NGC 7174 which appears severely distorted by the ongoing
interaction with NGC 7173.
