摘要: Using a phenomenological form of the equation state neutron matter near saturation density which has been previously demonstrated to be good characterization quantum Monte Carlo simulations, we show that currently available star mass and radius measurements provide significant constraint on matter. At higher densities model by using polytropes quark model. We observations offer an important strength three-body force in matter, thus some theoretical models may ruled out astrophysical data. In addition, obtain estimate symmetry energy nuclear its slope can directly compared experiment other calculations.
