The Carina Project. V. The impact of NLTE effects on the iron content
M. Fabrizio, T. Merle, F. Thévenin +21
We have performed accurate iron abundance measurements for 44 red giants (RGs) in the Carina dwarf spheroidal (dSph) galaxy. We used archival, high-resolution spectra (R~38,000) co…
Stroemgren photometry of the Bulge: the Baade's Window and the globular cluster NGC 6522
A. Calamida, G. Bono, C. E. Corsi +11
We present Ca-uvby Stroemgren photometry of the Baade's Window, including the Galactic globular cluster NGC 6522. We separate field and cluster stars by adopting color-color planes…
On a new theoretical calibration of the Stroemgren hk metallicity index: NGC6522 as a first test case
A. Calamida, G. Bono, C. Corsi +11
We present a new theoretical calibration of the Stroemgren metallicity index hk by using alpha-enhanced evolutionary models transformed into the observational plane by using atmosp…
On a new parameter to estimate the helium content in old stellar systems
F. Troisi, G. Bono, P. B. Stetson +19
We introduce a new parameter Δξ - the difference in magnitude between the red giant branch (RGB) bump and a point on the main sequence (MS) at the same color as the bump, the "benc…
The Carina Project. IV. radial velocity distribution
M. Fabrizio, M. Nonino, G. Bono +16
We present new and accurate radial velocity (RV) measurements of luminous stars of all ages (old horizontal branch, intermediate--age red clump, and young blue plume, as well as re…
On the absolute age of the Globular Cluster M92
A. Di Cecco, R. Becucci, G. Bono +15
We present precise and deep optical photometry of the globular M92. Data were collected in three different photometric systems: Sloan Digital Sky Survey (g',r',i',z'; MegaCam@CFHT)…
