Descripción
We present both space (ACS@HST: F814W, F606W, F475W) and ground-based (MEGACAM@CFHT: u*, g',i',r',z') photometry of the Galactic Globular Cluster (GGC) M92. Space data are located close to the cluster center, while the ground-based data cover one square degree around the cluster center. We investigate the ratios between Horizontal Branch (HB), Main Sequence (MS) and Red Giant Branch (RGB) stars across the body of the cluster. We found that the star counts agree quite well with the predicted evolutionary lifetimes.

    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

    The TESS TTV Follow-up Program: Revealing Volatile-Rich Terrestrial Planets Around M Stars
    Models predict that water-rich planets may be common around low-mass stars, but definitive evidence for the existence of water worlds has remained elusive. Recent JWST observations of sub-Neptune sized planets orbiting nearby M dwarfs found atmospheres enriched in CH4, CO2 and H2O, but the enrichment mechanism is debated. To answer this question

    The instrumentation plan of the 10.4m GTC telescope
    The 10.4m Gran Telescopio Canarias (GTC) was designed to be a versatile telescope, able to serve a wide scientific community. To this aim, various focal stations have been equipped, including a Cassegrain, two Nasmyth foci, and four folded-Cassegrain stations. This allows an ambitious instrumentation plan to be developed. We present the latest
