Perhaps in the Eta Carinae system there were three stars and one of them was destroyed

Two articles published in the journal “The Monthly Notices of the Royal Astronomical Society” describe different aspects of a research that offers an explanation to the Great Eruption, an event in which the brightness of the Eta Carinae system increased between 1820 and 1843. A team of astronomers used various telescopes to gather new information about what’s happened in that area, concluding that originally there were three stars whose interaction ended up leading to the destruction of one of them.
