Descripción
We analyze the observed properties of nested and single stellar bar
systems in disk galaxies. Our sample consists of 56 Seyfert and 56
non-Seyfert galaxies. We use HST H-band images of the central parts and
ground-based images of the outer parts with ellipse fitting to find
bars. Our main result is a clear division between the secondary and
primary bars in terms of bar length. We show that single bars have
different properties from nested bars. We also confirm a statistically
significant prevalence of bars among the Seyfert galaxies when compared
to non-Seyfert galaxies.
