The Sun provides a standard reference against which we compare the chemical abundances found anywhere else in the Universe. Nevertheless, there is not a unique...
CHromospheric magnetic fields in fLAREs and their evolution CHLARE
This project aims to study the variations of the solar magnetic field in flares, the most energetic events in our solar system. Flares accelerate charged...
Fast-to-Alfvén Mode Conversion and Ambipolar Heating in Structured Media. II. Numerical Simulation
This paper studies the effectiveness of production of Alfvén waves in the solar atmosphere through the processes of mode conversion, taking into account several...
How to determine the quality of solar granulation images: The optimal window method
An optimal window for image analysis is determined by means of information theory. The size of the window is then used as a good estimator of image quality. The...
Long Characteristics versus Short Characteristics in 3D Radiative Transfer Simulations of Polarized Radiation
We compare maps of scattering polarization signals obtained from three-dimensional (3D) radiation transfer calculations in a magnetoconvection model of the...
The European Solar Telescope (EST) is a project of a new-generation solar telescope. It has a large aperture of 4 m, which is necessary for achieving high...
Researchers have observed the heating produced in the Sun by magnetic waves
An international team in which researchers from the Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL) are participating...
The IAC organises the CLASP2.1 space mission scientific meeting
From 18 to 20 October, scientists from the USA, Japan and Europe meet at the Instituto de Astrofísica de Canarias (IAC) to discuss the results of the third...
The Impact of Limited Time Resolution on the Forward-scattering Polarization in the Solar Sr I 4607 Å Line
Theoretical investigations predicted that high spatiotemporal resolution observations in the Sr I 4607 Å line must show a conspicuous scattering polarization...
