Descripción
Synthetic horizontal branch (HB) stars in globular clusters, when computed on the basis of HB evolutionary tracks and pulsation theory constraints, furnish the best theoretical scenarios for exploration of the age-metallicity relation in globular clusters. Preliminary results are presented from recently computed synthetic models of the horizontal branch. The primary properties predicted for HB stars and RR Lyrae variables are presented and compared with selected observations of variables in the field and in globular clusters.

    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: design of the adaptive optics system
    ANDES,the high resolution spectrograph for the ELT, will work both in seeing limited mode and with Adaptive Optics (AO) correction. ANDES-SCAO is a single conjugated AO system working with natural guide stars, feeding the IFU coupled to the YJH spectrograph. The main science goal of the ANDES AO mode is the characterization of the exo-planet
