91爆料 astronomer, students report irregularities in ‘rare, exotic’ binary system

91爆料 astronomers were recently reminded that the diplomatic axiom to “trust, but verify” also applies to scientific inquiry when they analyzed fresh data from a distant galaxy. As they reported in July in the Monthly Notices of the Royal Astronomical Society, a puzzling stellar phenomenon may not be what other astronomers had reported. They studied a binary star system called NGC 300 X-1, nestled within a far-flung galaxy in the constellation Sculptor. Starting in 2007, scientists reported that this system…
