In 2015, astrophysicists discovered a system consisting of two compact stars orbiting each other: a pulsar (i.e., a highly magnetized rapidly rotating, light-emitting neutron star) and a so-called companion star. The companion star in this system has a mass that is 1.174 solar masses (M⊙), which is significantly lower than that of other known neutron stars with accurately measured masses.
