neutron equation smooth causality first-order phase transitionRésumé
Causality is an essential factor in determining the maximum mass of a neutron star.
Previous works study causality for smooth equations of state.
The density at the core of neutron stars can be a few times nuclear saturation density, where the occurrence of first-order phase transition has not been ruled out.
The causality condition for first-order phase transition is characteristically different from that of smooth EOS, which becomes evident in the mass-radius relation.
In this letter, we find that equations of state having first-order phase transition, the causality line deviates considerably from the smooth equation of state.
Depending on the onset density of phase transition, there is a narrow band in the mass-radius plot, which is available only to the stars having a smooth equation of state.
This can have significant consequences in the sense that if some pulsars are to lie in this band, one can rule out the equation of state having first-order phase transition occurring at that particular onset density.
