Massive Neutron Stars


The Shapiro delay for PSR J1614-2230 indicates that it is the most massive neutron star yet.   The result appears more robust than the last most massive neutron star.  If it is indeed just under two solar mass, this has lots of consequences for the neutron star equation of state.   If in the future additional relativistic effects are measured, this tantalizing result may become even more robust (or go away).
