Chemically peculiar stars
Peculiar stars in globular clusters
The existence of peculiar stars at the Blue Horizontal Branch was already shown by
Behr et al. 1999.
He used high resolution spectra to determine elemental
abundances of individual objects to prove the peculiarity. Our technique is capable to
cover simultaneously all members of a globular cluster. A preliminary result of our
photometric survey by means of M30, where a few peculiar stars were found with the aid
of a photometry, is shown in this Figure.
