Na-O Anticorrelation and HB. VII. The chemical composition of first and second-generation stars in 15 globular clusters from GIRAFFE spectra
E. Carretta, A. Bragaglia, R. G. Gratton +12
We present abundances of Fe, Na, and O for 1409 red giant stars in 15 galactic globular clusters, derived from the homogeneous analysis of high resolution FLAMES/GIRAFFE spectra. C…
Structural Parameters of Seven SMC Intermediate-Age and Old Star Clusters
Katharina Glatt, Eva K. Grebel, John S. Gallagher III. +9
We present structural parameters for the seven intermediate-age and old star clusters NGC121, Lindsay 1, Kron 3, NGC339, NGC416, Lindsay 38, and NGC419 in the Small Magellanic Clou…
Galaxies at z = 6 - 9 from the WFC3/IR imaging of the HUDF
R. J. McLure, J. S. Dunlop, M. Cirasuolo +5
We present the results of a systematic search for galaxies in the redshift range z = 6 - 9, within the new, deep, near-infrared imaging of the Hubble Ultra Deep Field provided by t…
Star Formation History of the SMC: six HST/ACS
E. Sabbi, J. S. Gallagher, M. Tosi +9
We observed six fields of the Small Magellanic Cloud (SMC) with the Advanced Camera for Survey on board the Hubble Space Telescope in the F555W and F814W filters. These fields samp…
On the stellar content of the starburst galaxy IC10
N. Sanna, G. Bono, P. B. Stetson +17
We investigate the stellar content of the starburst dwarf galaxy IC10 using accurate and deep optical data collected with the Advanced Camera for Surveys and with the Wide Field Pl…
Star formation history in the SMC: the case of NGC602
M. Cignoni, E. Sabbi, A. Nota +9
Deep HST/ACS photometry of the young cluster NGC 602, located in the remote low density "wing" of the Small Magellanic Cloud, reveals numerous pre-main sequence stars as well as yo…
