Recent studies on the comparison between the Multi Aperture Scintillation Sensor (MASS) and Generalized Scintillation Detection and Ranging (G-SCIDAR) profiler techniques have suggested significant discrepancies between the results delivered by the two instruments. MASS has been largely used in the recent site testing campaigns for the future next

In the context of the Transit Monitoring in the South project, we present nine new transit observations of the exoplanet OGLE-TR-113b observed with the Gemini South, Magellan Baade, Danish-1.54 m and Southern Astrophysical Research telescopes. We perform a homogeneous analysis of these new transits together with 10 literature transits to probe into

Context. During the past 30 years the surface of Pluto has been characterized and its variability monitored through continuous near-infrared spectroscopic observations. But in the visible range only a few data are available. Aims: The aim of this work is to define Pluto's relative reflectance in the visible range to characterize the different

We performed a detailed study of the evolution of the luminosity of He-ignition stage and of the red giant branch bump luminosity during the red giant branch phase transition for various metallicities. To this purpose we calculated a grid of stellar models that sample the mass range of the transition with a fine mass step equal to 0.01 M⊙. We find
