Fredagskollokvium: Science with the European Solar Telescope

 Ada Ortiz-Carbonell, Researcher, ITA

The European Solar Telescope (EST) is a next-generation 4-m solar telescope that will be constructed
in the Canary Islands (Spain) starting in 2021. It is being promoted by the European Association
for Solar Telescopes (EAST), a consortium of 23 institutions from 17 European countries. EST is
included on the ESFRI Roadmap since 2016 and is therefore recognized as a research infrastructure
of strategic interest for Europe. In preparation for the construction phase, EAST has set up a Science
Advisory Group (SAG) whose task is to update the EST science requirements taking into account the capabilities
of the instruments defined in previous phases. EST is optimized for high-precision polarimetric and multi-wavelength
capabilities of the lower solar atmosphere at a spatial resolution of around 50 km. Its main goal is to examine the magnetic coupling in the solar atmosphere from the deepest layers of the photosphere to the highest layers of the chromosphere. All the instruments will operate strictly simultaneously
to provide seamless coverage of the photosphere and the chromosphere at the highest cadence ever
achieved for this type of measurements. The currently envisaged EST instrument suite consists of
4 grating spectropolarimeters and 5 narrow-band tunable filters working in visible and near-infrared
wavelengths, plus 3 broad-band imagers. In this talk, I will present examples of the unique science
to be enabled by EST.
