Abstract:
It is an observational fact that bulges of spiral galaxies contain a
high fraction of old and metal-rich stars. Following this
observational fact, we have investigated the colors of 21 bulges
hosted by a selected sample of high surface brightness spiral galaxies
and low surface brightness galaxies observed in the B and R optical
bands and the J and Ks near-IR bands.
Description:
Optical observations were strictly performed during photometric nights
in three runs at Las Campanas Observatory, using the 2.5m du Pont
telescope. The first two runs took place in 2000 April and August, and
the third one was in 2002 April.
