SUMMARY:Academic Spanish Course for Foreigners (2025)
DESCRIPTION:The Academic Spanish course for foreigners is designed to facilitate effective communication in academic and profesional contexts. Through a practical and personalized focus\, the participants will develop essential linguistic abilities to discuss scientific articles\, participate in conferences\, give presentations\, and collaborate in international projects. The program includes technical vocabulary\, beginner and advanced grammar\, and simulations of real-life situations. Moreover\, it will promote the cultural immersion to strengthen the comprehension of the Hispanic world\, and their impact on interdisciplinary investigation and collaboration. \nThis course will be taught throughout in the following blocks: \nJanuary 21st – February 27thApril 22nd – May 29thSeptember 23rd – October 30thThe course is taught by Prof. Nazira Ruíz

SUMMARY:SO IAA course: Dynamo Theory in Astrophysics
DESCRIPTION:Magnetic fields are ubiquitous in the Universe\, including the geomagnetic field\, the systematic magnetic field responsible for the eleven year solar activity cycle\, and the magnetic fields of planets\, stars\, galaxies and accretion disks. It is now generally accepted that these fields are created by the action of hydromagnetic dynamos; i.e. by the motions of conductive fluids or plasmas that sustain the field against the action of Ohmic dissipation. For all these objects there is no ab initio predictive theory for the origin of their magnetic fields. Since the 1950s\, mean-field electrodynamics explains sustained large-scale astrophysical magnetic fields through systematic stretching and twisting of magnetic field lines by turbulent flows. This process is efficient when velocity and magnetic field fluctuations correlate well\, so that net electromotive force is non-zero.  This is possible for flows which possess a high degree of asymmetry and linkedness. Astrophysical rotating turbulence often complies with this assumption\, however\, high flow complexity of the flow means that analytical dynamo solutions are very challenging to derive. 3D numerical simulations became and remain the main tool of dynamo modelling. \nFollowing the footsteps of Andrei Kolmogorov and Keith Moffatt\, in this short course we aim to introduce you to the basics of turbulence and mean-field dynamo theory\, as well as their link to recent numerical simulations\, and the perspectives for astrophysics. The course will be delivered in English\, although the discussion and questions in Spanish are welcome.

SUMMARY:SO Colloquium: The multiple aspects of Star-Planet Interactions
DESCRIPTION:Star-Planet Interactions (SPIs) encompass a range of physical processes that occur in close-in exoplanetary systems\, where the proximity between a star and its planet leads to complex magnetic\, gravitational\, and atmospheric effects. These interactions can influence both stellar activity and planetary evolution\, making them crucial to our understanding of exoplanetary environments\, habitability\, and observational signatures across multiple wavelengths. One key aspect of SPIs is their impact on the magnetic activity of the host star. Close-in planets\, particularly those orbiting magnetically active stars\, can modify the star’s magnetosphere\, potentially enhancing or suppressing stellar activity through mechanisms such as magnetic reconnection or tidal interactions. This could lead to observable changes in stellar spots\, flares\, and coronal mass ejections\, affecting not only the planet itself but also the broader space weather conditions of the system. On the planetary side\, interactions with the stellar magnetic field and wind can generate radio emissions\, providing a potential way to detect and characterise exoplanetary magnetospheres. These emissions\, similar to auroral radio signals observed in the Solar System (e.g.\, from Jupiter and its moons)\, could offer the first direct constraints on exoplanetary magnetic fields\, which play a fundamental role in shielding planetary atmospheres from erosion and determining their long-term habitability. In this seminar\, I will provide an overview of SPIs and their different manifestations\, discussing both the observational evidence and theoretical frameworks used to study these interactions. I will highlight the role of stellar magnetism in shaping SPI signals\, explain the challenges in detecting and interpreting these signatures\, and discuss how multi-wavelength observations—including optical\, X-ray\, and radio surveys—are helping us advance our understanding of exoplanetary atmospheres\, magnetic fields\, and their interaction with their host stars. \nFecha: 17/06/2025 – 12:30Dr. Rim FaresFiliación: United Arab Emirates University\, UAE \n
