One of the most intriguing questions about neutron stars concerns their maximum mass. The answer is intimately related to the properties of matter at densities far beyond that found in heavy atomic nuclei. The current view on the internal constitution of neutron stars and on their maximum mass, both from theoretical and observational studies, are briefly reviewed.

Maximum pulsar mass, equation of state and structure of neutron-star cores
The structure of neutron stars is determined by the equation of state of dense matter in their interiors. Brief review of the equation of state from neutron star surface to its center is presented.…
Constraints on the speed of sound of dense nuclear matter through the tidal deformability of neutron stars
One of the greatest interest and open problems in nuclear physics is the upper limit of the speed of sound in dense nuclear matter. Neutron stars, both in isolated and binary system cases, constitute…
Gravitational antiscreening in stellar interiors
A new class of relativistic stellar structure equations which include the effects of an energy-dependent Newton coupling is presented. Significant modifications in the mass-radius relation for…
Speed of sound constraints on maximally rotating neutron stars
The observation of maximally rotating neutron stars (in comparison to nonrotating ones) may provide more information on the behavior of nuclear matter at high densities. We provide a theoretical…

Neutron stars structure in the context of massive gravity
Motivated by the recent interests in spin−2 massive gravitons, we study the structure of neutron star in the context of massive gravity. The modifications of TOV equation in the presence of massive…
Speed of sound constraints from tidal deformability of neutron stars
The upper bound of the speed of sound in dense nuclear matter is one of the most interesting but still unsolved problems in Nuclear Physics. Theoretical studies in connection with recent…

Inverse chameleon mechanism and mass limits for compact stars
As is well known, there are various mass limits for compact stars. For example, the maximum mass for non-rotating white dwarfs is given by the famous Chandrasekhar limit about 1.4 M ☉ (solar masses).…
Distinguishing double neutron star from neutron star-black hole binary populations with gravitational wave observations
Gravitational waves from the merger of two neutron stars cannot be easily distinguished from those produced by a comparable-mass mixed binary in which one of the companions is a black hole. Low-mass…

On the maximum mass of a neutron star
On the basis of Einstein's theory of relativity, the principle of causality, and Le Chatelier's principle, it is here established that the maximum mass of the equilibrium configuration of a neutron…
The maximum mass of a neutron star
Observational identification of black holes as members of binary systems requires the knowledge of the upper limit on the gravitational mass of a neutron star. We use modern equations of state for…

We calculate neutron star models using four realistic high-density models of the equation of state. We conclude that the maximum mass of a neutron star is unlikely to exceed 2 M/sub sun/. All of the…
One possible mechanism for massive neutron star supported by soft EOS
The recently discovery of a massive neutron star (PSR J1614-2230 of 1.97 ± 0.04 M⊙) rules out the soft equation-of-states (EOSs) such as those included hyperons or kaon condensates at high densities,…

The Limiting Mass of a Neutron Star
ASSUMING that pulsars are spinning, contracted stellar objects of enormous mass, we can divide the interior of a pulsar into three distinct density regions. Region 1 has a density below 5 × 1011 g…
A two-solar-mass neutron star measured using Shapiro delay
TLDR
Radio timing observations of the binary millisecond pulsar J1614-2230 that show a strong Shapiro delay signature are presented and the pulsar mass is calculated to be (1.97 ± 0.04)M⊙, which rules out almost all currently proposed hyperon or boson condensate equations of state.
