Boson stars in the centre of galaxies?
We investigate the possible gravitational redshift values for boson stars
with a self-interaction, studying a wide range of possible masses. We find a
limiting value of z_lim \simeq 0.687 for stable boson star configurations. We
can exclude the direct observation of boson stars. X-ray spectroscopy is
perhaps the most interesting possibility
