The O-Na and Mg-Al Anticorrelations in Turn-Off and early Subgiants in Globular Clusters
R. G. Gratton, P. Bonifacio, A. Bragaglia +16
High dispersion spectra (R>40,000) for a quite large number of stars at the main sequence turn-off and at the base of the subgiant branch in NGC6397 and NGC6752 were obtained with…
CU Comae: a new field double-mode RR Lyrae, the most metal poor discovered to date
G. Clementini, S. Di Tomaso, L. Di Fabrizio +12
We report the discovery of a new double-mode RR Lyrae variable (RRd) in the field of our Galaxy: CU Comae. CU Comae is the sixth such RRd identified to date and is the most metal-p…
On the Existence of Differences in Luminosity between Horizontal Branch Stars in Globular Clusters and in the Field
Eugenio Carretta, Raffaele Gratton, Gisella Clementini
The discrepancy between a LONG distance scale derived from Hipparcos based distances to globular clusters via main sequence fitting to local subdwarfs, and a SHORT distance scale d…
