Two articles published in “The Astrophysical Journal” reports two studies on the supernova SN 1987A remnants. Two teams of researchers led by Phil Cigan of the British University of Cardiff and Dany Page of the National Autonomous University of Mexico respectively used observations conducted with the ALMA radio telescope and follow-up theoretical studies to bring evidence that a neutron star formed after the supernova. If these results are confirmed, it would be the youngest known neutron star.
