Descripción
We study the problem of the generation and transfer of spectral line intensity and polarization in models of stellar atmospheres with horizontal plasma inhomogeneities. We solve the non-LTE radiative transfer problem in full 3D geometry taking into account resonant scattering polarization and its modification by magnetic fields via the Hanle effect. We show that horizontal fluctuations of the thermodynamical conditions of stellar atmospheres can have a significant impact on the linear polarization of the emergent spectral line radiation and its center-to-limb variation.

Magnetismo, Polarización y Transferencia Radiativa en Astrofísica
Los campos magnéticos están presentes en todos los plasmas astrofísicos y controlan la mayor parte de la variabilidad que se observa en el Universo a escalas temporales intermedias. Se encuentran en estrellas, a lo largo de todo el diagrama de Hertzsprung-Russell, en galaxias, e incluso quizás en el medio intergaláctico. La polarización de la luz

    Conceptual design of the infrared integral field spectropolarimeter for the European Solar Telescope
    The European Solar Telescope (EST) will be Europe's most ambitious ground-based infrastructure in solar physics. It will have a primary mirror with a diameter of 4.2m, which will make it the largest in Europe, and of identical aperture as the largest solar telescope available worldwide, namely the Daniel K. Inouye Telescope (DKIST) installed at the

    Detector upgrade in EMIR@GTC: on-sky performances
    EMIR was shipped to the GTC on May 2016 and had its first light on June 2016. Since the beginning, the EMIR performances have been severely hampered by the many instabilities in the infrared detector, a 2048x2048 Hawaii2, built with the old original technology of the Teledyne Hawaii series. Despite of this, the instrument has proven to be powerful

    The Large Interferometer For Exoplanets (LIFE): a space mission for mid-infrared nulling interferometry
    The Large Interferometer For Exoplanets (LIFE) is a proposed space mission that enables the spectral characterization of the thermal emission of exoplanets in the solar neighborhood. The mission is designed to search for global atmospheric biosignatures on dozens of temperate terrestrial exoplanets and it will naturally investigate the diversity of
