    Dissecting light bridges: the stratification of their physical properties in geometric height
    Light bridges are elongated and bright structures protruding into the umbra of sunspots. The presence of light bridges has a significant role in the evolution of sunspots and the heating of their overlying atmosphere. Therefore, investigating these structures is crucial to understanding fundamental aspects of sunspots. By applying a novel code based on deep-learning algorithms called SICON to spectropolarimetric observations acquired with the Hinode satellite, we computed atmospheric parameters that allowed us to infer the variation of the physical properties of light bridges on a geometric

    The IAC and the ULL participate in the discovery of an unusual ‘stellar dance’ that could culminate in an explosion visible from Earth
    A greedy white dwarf star in our own Milky Way galaxy is devouring its closest celestial companion at a rate never seen before, according to an international study involving the Instituto de Astrofisica de Canarias (IAC) and the University of La Laguna (ULL). The research, published in the journal Monthly Notices of the Royal Astronomical Society , found the double star, named V Sagittae, is burning unusually bright as the super-dense white dwarf is gorging on its larger twin in a feeding frenzy. Experts think the stars are locked in an "extraterrestrial tango" as they orbit each other every
