    The PLATO 2.0 mission

    PLATO 2.0 has recently been selected for ESA’s M3 launch opportunity (2022/24). Providing accurate key planet parameters (radius, mass, density and age) in statistical numbers, it addresses fundamental questio...

    Milli-arcsecond Astrophysics with VSI, the VLTI Spectro-imager in the ELT Era

    Nowadays, compact sources relatively warm like surfaces of nearby stars, circumstellar environments of stars from early stages to the most evolved ones and surroundings of active galactic nuclei can be investi...

    Prospects for Near-infrared Characterisation of Hot Jupiters with the VLTI Spectro-imager (VSI)

    Since the discovery of the first exoplanet around 51 Pegasi, the study of planetary systems receives an increasing attention, with the development and test of more and more detection techniques. Among the dire...

    Planet Detection Around M Dwarfs: New Constraints on Planet Formation Models

    The dependence of planetary statistics on the physical conditions during the initial stages of the system (i.e. in the proto-planetary disk) represent an essential constraint on planetary formation mechanisms....

    In Quest of Very Low Mass Stars and Brown Dwarfs with Near-IR Surveys

    Deep large scale near-infrared surveys have started revolutionizing the study of very low mass stars and brown dwarfs (hereafter VLMS and BD) by producing, for the first time, statistically significant samples...

    The Molecular Envelopes of Planetary Nebulae

    We report the results of an extensive survey of molecular gas in planetary nebulae (PNe) using the millimeter lines of CO. The observations provide a range of information on the kinematics, the structure, and ...

    Inhibition of giant-planet formation by rapid gas depletion around young stars

    ALTHOUGH stars form from clouds of gas and dust, there are insig-nificant amounts of gas around ordinary (Sun-like) stars. This suggests that hydrogen and helium, the primary constituents of planets such as Ju...

    The Spatio-Kinematic Structure of the CO Envelopes in Evolved Planetary Nebulae

    We report high angular resolution map** of the CO (J=2→1 and 1→0) lines in three evolved planetary nebulae (PNe): NGC 6781, NGC 6772, and VV 47. The CO 2→1 observations of the ring-like nebula NGC 6781 provide ...
