    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
