Descripción
In this paper, the present status of the development of the design of
the European Solar Telescope is described. The telescope is devised to
have the best possible angular resolution and polarimetric performance,
maximizing the throughput of the whole system. To that aim, adaptive
optics and multi-conjugate adaptive optics are integrated in the optical
path. The system will have the possibility to correct for the diurnal
variation of the distance to the turbulence layers, by using several
deformable mirrors, conjugated at different heights. The present optical
design of the telescope distributes the optical elements along the
optical path in such a way that the instrumental polarization induced by
the telescope is minimized and independent of the solar elevation and
azimuth. This property represents a large advantage for polarimetric
measurements. The ensemble of instruments that are planned is also
presented.

Magnestismo Solar y Estelar
Los campos magnéticos son uno de los ingredientes fundamentales en la formación de estrellas y su evolución. En el nacimiento de una estrella, los campos magnéticos llegan a frenar su rotación durante el colapso de la nube molecular, y en el fin de la vida de una estrella, el magnetismo puede ser clave en la forma en la que se pierden las capas
