    Researchers from the IAC and the ULL achieve the most accurate measurement to date of a key layer inside the Sun
    An international team composed of Drs. Sylvain G. Korzennik, from the Center for Astrophysics | Harvard & Smithsonian , and Antonio Eff-Darwich Peña, from the University of La Laguna and the Instituto de Astrofísica de Canarias, has published a pioneering study aimed at improving our understanding of the Sun’s internal structure. The work, published in The Astrophysical Journal , stands out for its use of exceptionally long helioseismic time series, exceeding twenty-five years of continuous observations, to analyze the deepest layers of the Sun. Helioseismology is the study of patterns of

    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
