Descripción
The European Solar Telescope (EST) will be equipped with a MCAO system to provide an excellent correction within one arcminute field of view (FOV). A prototype of this system will be built with the same requirements except for the frame rate. This prototype will allow to test and verify new concepts for Solar MCAO, as, e.g., the integration of neuronal networks in the reconstruction process. This prototype will work as follows: a high-resolution image of the sun will be created and perturbed by a turbulence simulator with different phase screens placed at different heights. MCAO correction will be performed by one pupil DM and four altitude DMs. Two wide field wavefront sensors will be used to perform the tomography. The calibration and control strategies are still to be defined in the lab for the future implementation on the EST MCAO system. A scientific camera will evaluate the performance on a 60" field. The prototype is currently under construction and it is expected to be finished by 2019.

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
