Equation of State in Numerical Relativistic Hydrodynamics [PDF]
, 2006 Relativistic temperature of gas raises the issue of the equation of state (EoS) in relativistic hydrodynamics. We study the EoS for numerical relativistic hydrodynamics, and propose a new EoS that is simple and yet approximates very closely the EoS of ...

Multimessenger constraints on the neutron-star equation of state and the Hubble constant
Science, 2020 A combined multimessenger analysis Neutron stars are stellar remnants with densities greater than that of an atomic nucleus. The properties of matter under such extreme conditions are poorly understood and inaccessible to terrestrial laboratories ...

QCD equation of state at finite chemical potentials for relativistic nuclear collisions [PDF]
International Journal of Modern Physics A, 2021 We review the equation of state of QCD matter at finite densities. We discuss the construction of the equation of state with net baryon number, electric charge, and strangeness using the results of lattice QCD simulations and hadron resonance gas models.

Masses, Radii, and the Equation of State of Neutron Stars [PDF]
, 2016 We summarize our current knowledge of neutron-star masses and radii. Recent instrumentation and computational advances have resulted in a rapid increase in the discovery rate and precise timing of radio pulsars in binaries in the past few years, leading ...

Equation of State in Relativistic Magnetohydrodynamics: variable versus constant adiabatic index [PDF]
, 2007 The role of the equation of state for a perfectly conducting, relativistic magnetized fluid is the main subject of this work. The ideal constant $\Gamma$-law equation of state, commonly adopted in a wide range of astrophysical applications, is compared ...

Neutron-Star-Merger Equation of State
Universe, 2019 In this work, we discuss the dense matter equation of state (EOS) for the extreme range of conditions encountered in neutron stars and their mergers. The calculation of the properties of such an EOS involves modeling different degrees of freedom (such as

P–V–T Equation of State of Iridium Up to 80 GPa and 3100 K
Crystals, 2021 In the present study, the high-pressure high-temperature equation of the state of iridium has been determined through a combination of in situ synchrotron X-ray diffraction experiments using laser-heating diamond-anvil cells (up to 48 GPa and 3100 K) and

A Seismic Equation of State [PDF]
Geophysical Journal International, 1967 Birch's hypothesis of a close relationship between seismic velocity and density is extended and modified so as to be in accord with theoretical predictions concerning the form of the equation of state. Although developed as a simple method to assure consistency between the seismic velocities and densities in free oscillation calculations the resulting ...

Neutron Star Cooling Within the Equation of State With Induced Surface Tension
Particles, 2020 We study the thermal evolution of neutron stars described within the equation of state with induced surface tension (IST) that reproduces properties of normal nuclear matter, fulfills the proton flow constraint, provides a high-quality description of ...
