Abstract:
The prints of the Palomar Sky Survey, luminosity classifications, and
radial velocities were used to assign all northern Shapley-Ames
galaxies to either (1) field, (2) group, or (3) cluster environments.
This information for 930 galaxies shows no evidence for a dependence
of bar frequency on galaxy environment. This suggests that the
formation of a bar in a disk galaxy is mainly determined by the
properties of the parent galaxy, rather than by the characteristics of
its environment.
