  • Artist’s impression of an ultra-hot Jupiter transiting its star

    An international team of astronomers, in which IAC researchers participate, have discovered barium, the heaviest element ever found in an exoplanet atmosphere. It has been discovered at high altitudes in the atmosphere of the exoplanets WASP-76 b and WASP-121 b, two ultra-hot gas giants. The unexpected discovery, made possible by the ESPRESSO instrument at the European Southern Observatory's Very Large Telescope (ESO's VLT), raises questions about what these exotic atmospheres may look like. WASP-76 b and WASP-121 b are no ordinary exoplanets. Both are referred to as ultra-hot Jupiters as

  • PANO

    El pasado sábado 1 de octubre tuvo lugar la segunda visita al Observatorio del Teide organizada por el programa #AmigosdelIAC, en el que algunos de los miembros de este programa pudieron conocer las instalaciones y observar el cielo a través de telescopios divulgativos. Si tienes interés en la labor del Instituto de Astrofísica de Canarias y aún no eres “Amigo del IAC”, puedes unirte a nuestro Programa respondiendo esta breve encuesta (https://cutt.ly/gBlVUFF), sin necesidad de que realices ninguna aportación. #AmigosdelIAC #IACastrofísica #InstitutodeAstrofísicadeCanarias #IAC #Tenerife

  • Stephan's Quintet

    Research led by the University of Oxford and with the participation of the Instituto de Astrofísica de Canarias (IAC) has succeeded in studying, for the first time, the tiny dust molecules known as polycyclic aromatic hydrocarbons (PAHs) in the nuclear region of luminous active galaxies. This work is one of the first studies to use spectroscopic data from the James Webb Space Telescope's (JWST) mid-infrared instrument (MIRI). Observing PAH molecules in the innermost regions of the galaxy is one of the best ways to study the influence of the central black hole in the evolution of the host

  • Sesión Erasmus Plus

    Fifteen students from nine different countries attended a meeting from September 26th to 30th to learn about the measurement of the fundamental properties of stars, how to access the publicly available data used to make these measurements as well as the tools and software involved. The Erasmus+ school "Eclipsing binaries and asteroseismology: Precise fundamental stellar parameters in the golden age of time-domain astronomy" was held in a hybrid format with fifteen students attending in-person and a further fifty via video conference. The latest advances in multi-epoch photometry and

    Puzzling properties of massive early-type galaxies (ETGs) emerge when studying their spectra at near-infrared (NIR) wavelengths. Massive ETGs show strong CO absorption features in their H and K band spectra that cannot be explained by state-of-the-art stellar population models. For many years, the disagreement has been attributed to the presence of intermediate-age (0.1-2 Gyr) stellar populations in these galaxies, as the NIR light of intermediate-age stellar populations is dominated by cool stars (e.g. asymptotic giant branch (AGB) stars) that show strong CO absorptions in their spectrum

  • Scientists and engineers from the institutions making up the consortium for building the EST have met in La Palma to evaluate the end of the preparatory phase. The European Solar Telescope (EST) project has finished the preliminary design phase of the sistemas and subsystems for what will be the largest solar telescope in Europe, in the framework of the european project PRE-EST. With its primary mirror of 4.2 metres diameter, the EST will be a unique driving force for solar research in Europe. It is planned to start construction in 2024, in the Roque de los Muchachos Observatory (La Palma
