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.
Cartlel de la conferecnia Solar MHD 2024
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.
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 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
Using observations made with the James Webb Space Telescope (JWST), an international scientific team, in which the Instituto de Astrofísica de Canarias (IAC) participates, has confirmed variations in morning and evening atmosphere of the exoplanet WASP-39 b, about 700 light-years away from Earth. The research has revealed differences in temperature and atmospheric pressure, as well as indications of different cloudiness and winds that could reach thousands of miles per hour. The results are published in Nature. WASP-39 b, a giant planet with a diameter 1.3 times greater than Jupiter, but
A team of scientists led by the Observatory of Munich University and the Instituto de Astrofísica de Canarias have obtained direct visualization of the process of feeding the supermassive black hole at the centre of the Andromeda galaxy. The study reveals the existence of long filamentary structures of gas and dust which move in a spiral starting at a distance from the black hole and ending up at the black hole itself. The results, which have been published in the Astrophysical Journal, were obtained using images from the Hubble and Spitzer space telescopes. The Andromeda Galaxy, which is
An international scientific team, in which researchers from the Instituto de Astrofísica de Canarias (IAC) participate, confirms that the asteroid, discovered with the Isaac Newton telescope at the Roque de los Muchachos Observatory (La Palma), follows an orbit synchronised with that of Jupiter, which reduces the probability of a collision with our planet in the coming decades. The celestial body is very solid, metallic, rotates ten times every hour and is about 40 metres long. The study is published in the journal Astronomy and Astrophysics. Asteroid 2023 DZ2, detected in February with the
