Two articles, one published in “The Astrophysical Journal Letters” and one published in the journal “Monthly Notices of the Royal Astronomical Society”, describe as many research on the supernova remnants known as RCW103. At its center a neutron star formed called 1E 161348-5055 – or simply 1E 1613 – that has been puzzling astronomers for decades for its abnormal behavior. Now two teams independently offered the same explanation: the neutron star has the characteristics of a magnetar.
