Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars. V. Evidence for a wide age distribution and a complex MDF
T. Bensby, J. C. Yee, S. Feltzing +20
Based on high-resolution spectra obtained during gravitational microlensing events we present a detailed elemental abundance analysis of 32 dwarf and subgiant stars in the Galactic…
Fluorine variations in the globular cluster NGC 6656 (M22): implications for internal enrichment timescales
Valentina D'Orazi, Sara Lucatello, Maria Lugaro +8
Observed chemical (anti)correlations in proton-capture elements among globular cluster stars are presently recognized as the signature of self-enrichment from now extinct, previous…
Searching for multiple stellar populations in the massive, old open cluster Berkeley 39
A. Bragaglia, R. G. Gratton, E. Carretta +3
The most massive star clusters include several generations of stars with a different chemical composition (mainly revealed by an Na-O anti-correlation) while low-mass star clusters…
The SEGUE K giant survey II: A Catalog of Distance Determinations for the SEGUE K giants in the Galactic Halo
Xiang-Xiang Xue, Zhibo Ma, Hans-Walter Rix +13
We present an online catalog of distance determinations for K giants, most of which are members of the Milky Way's stellar halo. Their medium-resolution spectra from SDS…
The Na-O anticorrelation in horizontal branch stars. III. 47 Tuc and M 5
R. G. Gratton, S. Lucatello, A. Sollima +7
To check the impact of the multiple population scenario for globular clusters on their HB, we present an analysis of the composition of 110 red HB (RHB) stars in 47 Tucanae and of…
The Ninth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-III Baryon Oscillation Spectroscopic Survey
III Collaboration, Christopher P. Ahn, Rachael Alexandroff +224
The Sloan Digital Sky Survey III (SDSS-III) presents the first spectroscopic data from the Baryon Oscillation Spectroscopic Survey (BOSS). This ninth data release (DR9) of the SDSS…
