| Abstract: |
We have observed 60 edge-on galaxies in the NIR in order to study the stellar distribution in the bulge. The much smaller amount of dust extinction at these wavelengths allows us to identify an additional thin, central component in cuts parallel to the major axis in almost all target galaxies with box/peanut shaped (b/p) bulges. These structures can be identified with a dynamically cold bar. The length of this structure correlates with the shape of the b/p bulge and is therefore interpreted as the projection of the bar at different aspect angles. In addition, a correlation between the bulge shape and the bar strength is found. |
