Are the Bulge C-stars related to the Sagittarius dwarf galaxy? II. Metallicity - a link with the galactic disc.

NG Y.K.

Abstract (from CDS):

The photometric estimate of the metallicity and the age of the Azzopardi et al. (1991A&AS...88..265A) carbon stars (Ng, 1997A&A...328..211N) is revised to respectively Z≃0.004 and ∼0.1Gyr. Under the hypothesis that the carbon stars are located at a distance related to the Sagittarius dwarf galaxy, the broad velocity dispersion of the stars can only be explained if they were formed out of Galactic material during a recent crossing of the Sagittarius dwarf galaxy through the Galactic plane.
