WebWe have built quasi-equilibrium models for uniformly rotating quark stars in general relativity. The conformal flatness approximation is employed and the Compact Object CALculator (cocal) code is extended to treat rotating stars with surface density discontinuity. In addition to the widely used MIT bag model, we have considered a … Webtransfer through the star, etc. Today we’re going to tackle the problem of pressure in stars, also known as the equation of state: an equation that specifies the pressure in a gas …

Also, if the nuclear burning is not stable, or the star's core is rapidly collapsing, an entropy term must be added to the energy equation. business publications in kenya
