Resumen:
Faint satellite galaxies are studied statistically using a sample
selection from the SDSS-DR4. Photometric and spectroscopic data in the
neighborhood of bright isolated galaxies are used. An excess in
projection of faint galaxies is found in the surrounding regions of the
hosts, to which those excess objects are suposed to belong to. Several
subsamples are analyzed in order to search for dependences on satellite
and host properties. The brightest hosts are found to have a profile
more rapidly vanishing.
