Descripción
We present the results of the analysis of the first black hole confirmed with GTC in the X-ray binary system XTE J1859+226. By combining optical photometry taken with the INT, WHT and NOT with long-slit spectroscopy with OSIRIS+GTC, we have obtained an orbital period of 6.58 h, a secondary star radial velocity amplitude of K_2=541±70 km s^-1 and an upper limit to the inclination of 70°, implying a black hole mass of at least 5.4 M⊙.

    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

    Design and manufacture of athermalized optomechanical mounts for GRANCAIN, the infrared imaging instrument for GTC's adaptive optics
    GRANCAIN (GRAN CAmara INfrarroja) is a first-light imaging instrument in the infrared J, H and K bands that will be integrated into the adaptive optics focus of the Gran Telescopio de Canarias. The purpose of the instrument is to capture SWIR diffraction-limited images for a field of view of 22x22 arcsec. The instrument boasts a telecentric optical
