Walecka Model

In this paper we use a polytropic approximation to the equation of state for the interior of neutrons stars, described by relativistic hadronic mean field models. In this approximation, it is possible to obtain analytic expressions for the sound velocity and the incompressibility at the star center. We found a correlation between these quantities and the star mass. Using two well-known parametrizations of the nonlinear Walecka model for nuclear matter composed only of protons, neutrons and electron in β equilibrium, we obtain for a star mass of 1.43 M⊙ a central incompressibility Kc = (3000±100), around ten times the nuclear matter incompressibility, and a central sound velocity (v/c)2 ~ 0.3.

New Equation

In this work the new kind of the equation of state expressing the density of sea water through independent and in situ measurable parameters: temperature, pressure and sound velocity, is justified theoretically and implemented in practice. The novelty of the approach is that the use of sound velocity as one of the arguments makes it possible measuring of the density of sea water without measurements of salinity. The developed equation reproduces the density of sea water with a high accuracy in a wide range of parameters.
