Description
Preliminary results are presented of spectroscopic analysis of ten young stars in OB associations using high resolution spectra and NLTE calculations. From the known distances the stellar masses are derived. The comparison with evolutionary tracks indicates a possible discrepancy between the masses and enhanced helium abundances derived from the tracks and from the analysis.

    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
