  • Cartel de la próxima sesión de Del Cielo a la tesis / IAC
    El Sol se convierte en protagonista en la nueva edición de Del cielo a la tesis en el MCC
    El Museo de la Ciencia y el Cosmos , del Organismo Autónomo de Museos y Centros del Cabildo de Tenerife, acogerá el próximo miércoles 23 de abril a las 17:00 horas una nueva entrega del ciclo de divulgación científica titulado “Del cielo a la tesis”, una iniciativa organizada por el alumnado del Instituto de Astrofísica de Canarias (IAC) y la Universidad de La Laguna (ULL). El ciclo, impulsado por estudiantado de doctorado del IAC, tiene como objetivo acercar a la ciudadanía los principales temas de investigación en Astrofísica narrados en primera persona por quienes los desarrollan.

    Appraising the Necklace: A post-common-envelope carbon dwarf inside an apparently carbon-poor planetary nebula
    The Necklace nebula is a bipolar, post-common-envelope planetary nebula, the central star of which has been shown to have a dwarf carbon star companion. We aim to understand the origins of the Necklace and its dwarf carbon central star. We study the carbon abundance of the nebula through far-ultraviolet spectroscopy obtained with the Hubble Space Telescope. Furthermore, through simultaneous modelling of multi-band light and velocity curves, we attempt to constrain the parameters of the central star system. Puzzlingly, we find that the region of the inner nebula observed with the Hubble Space

    DESI Completes Planned 3D Map of the Universe and Continues Exploring
    Last night, the 5,000 fibre-optic ‘eyes’ of the Dark Energy Spectroscopic Instrument (DESI) reached a major milestone, having fully covered the area originally planned for its map of the universe. Thus, DESI’s five-year programme has concluded ahead of schedule and with far more data than expected, resulting in the largest high-resolution 3D map of the universe ever produced. This map will enable researchers to explore dark energy, which accounts for 70% of the universe and drives its accelerated expansion. By comparing how galaxies were distributed in the past with their current

    Press release
    The IAC is involved in confirming the existence of an always-changing multi-planet system
    An international team of scientists, including researchers from the Canary Islands Institute of Astrophysics (IAC), has confirmed the existence of three bodies orbiting the dynamic exoplanetary system TOI-201. They include a super-earth (TOI-201 d), a warm Jupiter (TOI-201 b) and a brown dwarf (TOI-201 c). The paper is published in Science Advances. “The goal was to characterize the TOI-201 planetary system to understand not just what planets are there, but how they interact with each other dynamically,” said Ismael Mireles, a PhD candidate in the UNM Department of Physics and Astronomy and
