An article published in the journal “The Astrophysical Journal” describes the calculation of the maximum mass that a neutron star can reach. A team of astrophysicists from the Goethe University Frankfurt exploited what are considered universal relations between stars of that type and data collected in the event that saw the merger of two neutron stars observed at both gravitational waves and electromagnetic waves to establish that a non-rotating neutron star can’t exceed 2.16 solar masses.
