The Instituto de Astrofísica de Canarias (IAC) is hosting the second Solar MHD (UKUS 7) conference this week. Following the successful first edition held in Eastbourne (UK) in 2022, this event brings together nearly fifty international experts to discuss the latest advancements in solar magnetohydrodynamics.
Magnetohydrodynamics (MHD) is a branch of physics that studies the behavior of electrically conducting fluids, such as solar plasma. Understanding MHD processes in the Sun is essential for predicting phenomena like solar flares and coronal mass ejections, which can significantly impact Earth.
During the conference, participants will explore a wide range of topics, including: spectral synthesis and simulated data; machine learning in simulations and observations; using observations to establish boundary, initial conditions and constraints for MHD simulations; multi-fluid and partially ionised plasma models; enhanced MHD/hybrid models; and next generation of solar and stellar MHD simulations.
In addition to plenary and parallel sessions, the conference will include interactive sessions focused on the use of numerical codes and the diagnosis of solar plasma. These sessions will provide participants with the opportunity to share knowledge, establish collaborations, and explore new research avenues.
Magnetic fields are at the base of star formation and stellar structure and evolution. When stars are born, magnetic fields brake the rotation during the collapse of the mollecular cloud. In the end of the life of a star, magnetic fields can play a key role in the form of the strong winds that lead to the last stages of stellar evolution. During
POLMAG - Polarized Radiation Diagnostics for Exploring the Magnetism of the Outer Solar Atmosphere
POLMAG aims at a true breakthrough in the development and application of polarized radiation diagnostic methods for exploring the magnetic fields of the chromosphere, transition region and corona of the Sun.

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 particles into space, which may adversely affect satellites and Earth’s technology. Despite their clear importance for today’s technology, the timing and positioning when flares occur are so far
Most of the solar surface seems to be non-magnetic. However, it carries a magnetic flux and energy that easily exceed those of sunspots, plage and network all together. The solar magnetism studied so far represents only the 'tip of the iceberg'. The rest, known as 'magnetism of the quiet Sun' is been studied and characterized. The solar physicists of the IAC have played a leading role in this characterization, and the paper this highlight refers to points out a good example. Using the SST at the ORM, Sanchez Almeida et al. discovered, for the first time, magnetic bright points in the quiet
In a recently published differential analysis (see ApJ, 724, 1536, Dec. 1 issue) , we have derived abundance corrections for iron lines, using synthetic spectra from solar magnetoconvection simulations that were performed via running the Copenhagen stagger-code on massively-parallel clusters. The series of 3D snapshots used for the spectral synthesis covers 2.5 solar hours in the statistically stationary regime of the convection.Crucially, we show that the effect of magnetic fields on solar abundancedeterminations can not be neglected. This is equally valid for all three different Fe
The first Large-Sized Telescope (LST) prototype of the Cherenkov Telescope Array Observatory (CTAO), located at the Roque de los Muchachos Observatory (Garafía, La Palma), has made its first scientific discovery by detecting the source OP 313 above 100 gigaelectronvolts (GeV), a level of energy a billion times higher than the visible light that humans can perceive. It is the most distant quasar ever observed by gamma-ray instruments from the ground. On 15 December, the Large-Sized Telescope (LST) Collaboration announced through an Astronomer’s Telegram (ATel) the detection of the source OP
The 19th scientific meeting of CARMENES, a collaboration of more than 100 scientists from 11 Spanish and German institutions aimed at studying extrasolar planets around M-type dwarf stars, the lowest mass stars, was held this week at the IACTEC facilities in La Laguna (Tenerife, Spain). Since it became operational in 2016, CARMENES has analysed more than 360 such stars, leading to the discovery of more than 65 new planets, making it the most efficient instrument and mapper in the study of planets around very low-mass stars, with 30 % of the total number of planets discovered in this range
The Deputy Director of the IAC, Casiana Muñoz Tuñón praises the bravery and persistence shown by Francisco Sánchez which enabled the IAC to be recognized as one of the best centres in the world for research in astrophysics. The Instituto de Astrofísica de Canarias (IAC) hosted this morning the ceremony to rename the Centre of Astrophysics on La Palma (CALP) as CALP Francisco Sánchez, in honour of the person who was the first Professor of astrophysics in Spain, and the founder of the IAC. Those taking part in the ceremony included the Founding Director of the IAC, Francisco Sánchez Martínez
