The Old Halo metallicity gradient: the trace of a self-enrichment process
G. Parmentier, E. Jehin, P. Magain +2
Based on a model of globular cluster self-enrichment published in a previous paper, we present an explanation for the metallicity gradient observed throughout the galactic Old Halo…

The self-enrichment of galactic halo globular clusters : a clue to their formation ?
G. Parmentier, E. Jehin, P. Magain +3
We present a model of globular cluster self-enrichment. In the protogalaxy, cold and dense clouds embedded in the hot protogalactic medium are assumed to be the progenitors of gala…

Abundance correlations in mildly metal-poor stars
E. Jehin, P. Magain, C. Neuforge +3
Accurate relative abundances have been obtained for a sample of 21 mildly metal-poor stars from the analysis of high resolution and high signal-to-noise spectra. With these accurat…
