We present the first results from the mass modelling of the Sculptor dwarf spheroidal galaxy, using spectroscopic data from our VLT/FLAMES CaII triplet wide area survey of Sculptor.

The characteristics of ionized and H I gas in the peculiar star/cluster complex in NGC 6946, obtained with the 6-m telescope (BTA) Special Astrophysical Observatory Russian Academy of Sciences (RAS), the Gemini North telescope, and the Westerbork Synthesis Radio Telescope, are presented. The complex is unusual as hosting a super star cluster, the

We present here a part of the project aimed to study the SFH in different parts of the SMC. We observed 12 fields during a four year campaign (2001-2004) using the 100-inch Irénée du Pont telescope at Las Campanas Observatory, Chile, with positions ranging from ˜1° to ˜4° from the SMC center and located at different azimuths. In this poster we

We report the detection of transits by the 3.1 M_Jup companion to the V=8.17 G0V star HD 17156. The transit was observed by three independant observers on Sep. 9/10, 2007 (two in central Italy and one in the Canary Islands), who obtained detections at confidence levels of 3.0σ, 5.3σ, and 7.9σ, respectively. The observations were carried out under

For a number of reasons, the properties of integrated stellar populations are distributed. Traditional synthesis models usually return the mean value of such distribution, and a perfect fitting to observational data is sought for to infer the age and metallicity of observed stellar populations. We show here that, while this is correct on average

Colour-magnitude diagrams in the Washington system are presented for the first time for five star clusters projected on to the outer region of the Small Magellanic Cloud (SMC). The clusters are found to have ages in the range 0.1-1.0 Gyr, as derived from the fit of isochrones with Z = 0.004. This sample increases substantially the number of young
