Near-Infrared Photometry of Four Stellar Clusters in the Small Magellanic Cloud
Alessio Mucciarelli, Livia Origlia, Claudia Maraston +1
We present high-quality J, H and K photometry of four Small Magellanic Cloud stellar clusters with intermediate ages in the 1-7 Gyr range (namely NGC 339, 361, 416 and 419) . We ob…
The chemical composition of red giant stars in four intermediate-age clusters of the Large Magellanic Cloud
A. Mucciarelli, E. Carretta, L. Origlia +1
This paper presents the chemical abundance analysis of a sample of 27 red giant stars located in 4 popolous intermediate-age globular clusters in the Large Magellanic Cloud, namely…
The solar photospheric abundance of europium. Results from CO5BOLD 3-D hydrodynamical model atmospheres
A. Mucciarelli, E. Caffau, B. Freytag +2
Context. Europium is an almost pure r-process element, which may be useful as a reference in nucleocosmochronology. Aims. To determine the photospheric solar abundance using CO5BOL…
The intermediate-age globular cluster NGC 1783 in the Large Magellanic Cloud
A. Mucciarelli, L. Origlia, F. R. Ferraro
We present Hubble Space Telescope ACS deep photometry of the intermediate-age globular cluster NGC 1783 in the Large Magellanic Cloud. By using this photometric dataset, we have de…
The globular cluster NGC 1978 in the Large Magellanic Cloud
Alessio Mucciarelli, Francesco R. Ferraro, Livia Origlia +1
We have used deep high-resolution Hubble Space Telescope ACS observations to image the cluster NGC 1978 in the Large Magellanic Cloud. This high-quality photometric data set allowe…
Infrared photometry of Cepheids in the LMC clusters NGC 1866 and NGC 2031
Vincenzo Testa, Marcella Marconi, Ilaria Musella +6
Near infrared (IR) studies of Cepheid variables in the LMC take advantage of the reduced light curve amplitude and metallicity dependence at these wavelengths. This work presents s…
On the Iron content of NGC 1978 in the LMC: a metal rich, chemically homogeneous cluster
Francesco R. Ferraro, Alessio Mucciarelli, Eugenio Carretta +1
We present a detailed abundance analysis of giant stars in NGC 1978, a massive, intermediate-age stellar cluster in the Large Magellanic Cloud, characterized by a high ellipticity…
Red Giant stars in the Large Magellanic Cloud clusters
A. Mucciarelli, L. Origlia, F. R. Ferraro +2
We present deep J,H,Ks photometry and accurate Color Magnitude Diagrams down to K ~18.5, for a sample of 13 globular clusters in the Large Magellanic Cloud. This data set combined…
