Description
A three-dimensional model of the dust distribution in the Milky Way is presented based on FIR observations made by the COBE satellite. This model is a further development of that first presented by Drimmel & Spergel (2001). Here the molecular ring has been added, which shows evidence of ellipticity, as well as a central hole in the disk. Temperature gradients associated with the spiral arms have also been added. Description of dust within a few kiloparsecs of the Sun, associated with the local Orion arm, is further constrained by recent observations of nearby HII regions. Extinction along several lines-of-sight close to the Galactic plane is confronted with empirical measures using 2MASS data.

    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

    ANDES, the high resolution spectrograph for the ELT: science goals, project overview, and future developments
    The first generation of ELT instruments includes an optical-infrared high resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion Echelle Spectrograph). ANDES consists of three fibre-fed spectrographs ([U]BV, RIZ, YJH) providing a spectral resolution of ∼100,000 with a minimum simultaneous wavelength

    The European Solar Telescope (EST) is a 4-m class-solar telescope that will become part of the next generation of groundbased facilities. Located at the "Observatorio del Roque de los Muchachos" in La Palma (Spain), it will be aimed to study the magnetic connectivity of the solar atmosphere with high spatial and temporal resolution.
