In this presentation, we apply the Lava-ocean model that has been proposed for planets of the class of CoRoT-7b, i.e. rocky planets at a few stellar radii from their star, since Kepler-10b is a typical member of this family. The model predicts that the light from the planet has an important emission component in addition to the reflected one, even

Near-Earth asteroid 101955 (1999 RQ36; henceforth RQ36) is particularly interesting. It's especially accessible to spacecraft and is the primary target of NASA's OSIRIS-REx sample return mission; it's also a potentially hazardous asteroid (Milani et al. 2009). We combine dynamical and spectral information to identify the most likely main-belt

Near-Earth asteroid (162173) 1999 JU3 (henceforth JU3) is a potentially hazardous asteroid and the target of the Japanese Aerospace Exploration Agency’s Hayabusa-2 sample return mission. JU3 is also a backup target for two other sample return missions: NASA’s OSIRIS-REx and the European Space Agency’s Marco Polo-R. We use dynamical information to

Dwarf galaxies (Mb>-18) are important because of their cosmological interest as tests of hierarchical theories. The formation of these galaxies is still an open question but red dwarf galaxies are preferentially located in high density environments, indicating that they are end-products of galaxy transformations in clusters. Deep spectroscopic

Galaxy formation models typically assume that the size and rotation speed of galaxy discs are largely dictated by the mass, concentration and spin of their surrounding dark matter haloes. Equally important, however, is the fraction of baryons in the halo that collect into the central galaxy, as well as the net angular momentum that they are able to

Near-Earth asteroid 161273 (1999 JU3) is the primary target of the Japanese Aerospace Exploration Agency's Hyabusa-2 sample return mission. This object is also considered a potential target for two other sample return missions: the National Aeronautics and Space Administration's OSIRISREx and the European Space Agency's Marco Polo- R.
