The Nuclear Equation of State and Neutron Star Masses
... studies of pure neutron matter are limiting the properties of neutron star matter near the saturation density (usually expressed as baryon density, ns 0.16 baryons fm−3 ; mass density, ρs 2.7 × 1014 g cm−3 ; or energy density, εs 150 MeV fm−3 ). In this review, we show that estimates of the EO ...

On the evolution and fate of supermassive stars
... there are currently two models in favour. One involves the gradual accumulation of mass by accretion onto a seed black hole, which, while swallowing gas and stars in a stellar cluster, may grow to the intermediate mass range (see, e.g., Miller & Colbert 2004, and references therein). The other scena ...

In this case, the “classical” tidal and rotational effects that complicate the motion of other astrophysical objects and hide the (generally smaller) relativistic effects are simply absent, i.e., such systems are clean gravita ...

Detecting Stars at the Galactic Centre via Synchrotron Emission
