Description
The stellar content of the bulge of the Galaxy is not well characterized yet, in part due to the high extinction and, therefore, limited access at optical wavelengths. The SDSS-III Apache Point Observatory Galaxy Evolution Experiment (APOGEE) is an on-going near-infrared survey acquiring very high quality spectra (S/N > 100 per pixel, R 22,500) of 100,000 giant stars across the Galaxy. The APOGEE survey will enable a detailed exploration of parts of the bulge that are not chemically well known. We will show preliminary results of the composition of bulge stars collected in the first months of the survey. Metallicity distributions will be presented for different bulge fields and compared with results from the literature, where available.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta

    Local seeing analysis for the European Solar Telescope
    The European Solar Telescope (EST) will be built at the Observatorio del Roque de los Muchachos, a site known for its excellent atmospheric seeing conditions. The fundamental design of EST lies on two premises to improve the local seeing: placing the primary mirror as far as possible from the ground layer and using an open-air configuration. In

    First on-sky tests of LQG control for a 10m-class telescope: prelude on the Gran Telescopio Canarias adaptive optics system
    The Gran Telescopio Canarias (GTC) is being equipped with an Adaptive Optics (AO) system, developed by the Instituto de Astrofísica de Canarias (IAC). The Institut d'Optique Graduate School-Laboratoire Charles Fabry (IOGS-LCF), through a collaboration with the IAC, integrated some high performance control solutions. In this proceeding, we present
