Descripción
In this second paper dedicated to the study of satellite galaxies we
present broadband photometry in the B, V, R, and I filters of 49
satellite galaxies orbiting giant isolated spiral galaxies. First
analysis of the properties of these objects are presented by means of
color-color and color-magnitude diagrams for early- and late-type
satellites. Although we find differences in the slope of the V-I versus
Mv color magnitude diagram, as a whole, the relations are in
agreement with the trends known to date for galaxies of similar
magnitudes in nearby clusters of galaxies. Comparison with the relations
found for satellites in the Local Group allows us to sample better the
bright end of the luminosity function of satellite galaxies and extends
for brighter objects the validity of the color-magnitude relation found
for dwarf galaxies in the Local Group. Most of the E/S0 galaxies in our
sample show a negative color gradient with values similar to those known
for early-type galaxies in other environments.
