    IAC/ULL/CSIC | 15 January 2014 13:30

    Spanish scientists have discovered the first binary system ever known to consist of a black hole and a ‘spinning’ star – or more accurately, a Be-type star. Although predicted by theory, none had previously been found. The observations that led to the discovery were performed with the Liverpool and Mercator telescopes at the Observatorio del Roque de los Muchachos (Canary Islands, Spain).

  • White dwarfs hide information on dark forces

    SINC | 04 November 2013 08:54

    Researchers from Europe and the USA have ruled out a multitude of possible parameters for dark photons – a type of dark matter and energy – with the help of white dwarfs. In some aspects, the shining of these dying stars gives more information on dark forces than is provided by earth-based laboratories. The journal ‘Physical Review D’ has published the study.
