Descripción
We present a study of C, N, and O abundances for 24 unevolved metalpoor stars with metallicities in the range -0.3< [Fe/H]< -3. New C and N abundances have been measured using high resolution spectroscopy of the CH and NH bands at 3145 and 3360 Å, respectively. We also discuss the oxygen abundances obtained by Israelian et al. [10] for these stars and delineate the early Galactic evolution of these elements.

    HARMONI at ELT: HIPOTEC electronics and control system
    HARMONI is the first light visible and near-IR integral field spectrograph for the ELT. It covers a large spectral range from 470nm to 2450nm with resolving powers from 3300 to 18000 and spatial sampling from 60 mas to 4 mas. It can operate in two Adaptive Optics modes - SCAO (including a High Contrast capability) and LTAO - or with NOAO. The

    GTCAO low-frequency tip-tilt offload to M2
    GTCAO is the instrument that implements Adaptive Optics on GTC. For atmospheric turbulence correction, GTCAO uses a deformable mirror. Unlike other AO systems, GTCAO does not include a dedicated mirror for low-frequency tip-tilt (TT) correction. In the absence of dedicated correction, the TT components of atmospheric turbulence are corrected by the
