          Abstract

          Very recently a compact object with a mass in the range \(2.50\div 2.67\, M_{\odot}\) has been discovered via gravitational waves detection of a compact binary coalescence. The mass of this object makes it among the heaviest neutron star never detected or the lightest black hole ever observed. Here we show that a neutron star with this observed mass, can be consistently explained with the mass-radius relation obtained by Extended Theories of Gravity. Furthermore, equations of state, consistent with LIGO observational constraints, are adopted. We consider also the influence of rotation and show that masses of rotating neutron stars can exceed \(2.6 M_\odot\) for some equations of state compatible with LIGO data.
