With more than 80 transits observed in the CoRoT lightcurve with a cadence of 32 s, CoRoT-Exo-2b provides an excellent case to search for the secondary eclipse...

Jets from X-ray binaries are continuously injecting matter and energy into the surrounding interstellar medium. However, there exist to date relatively few...

The Sun has been suggested to have a slightly low refractory-to-volatile abundance ratio when compared with field solar twins. This result may be interpreted as...

It has been suggested that the outer young Galactic halo globular cluster population might be associated (or even the nuclei) to tidal disrupted dwarf...

The picture of building the Milky Way halo from the merger of protogalactic fragments is considered the local manifestation of the hierarchical galaxy formation...

The formation of the Galactic halo is currently best explained by the combination of two scenarios which previously were regarded as competing models. Based on...

We present preliminary results of a long-term project to investigate the process of accretion and tidal disruption of dSph satellites in the Galactic halo and...
