Description
Compact star observables are robust and not in one-to-one functional relationship with the microscopical parameters of the applied equation of state. This, the Masquarade problem, which means many types of equation of state parametrization and various parameter settings lead to the same macroscopic observation parameters.
So far we investigated a one-fermion-one-boson model with a simplistic Yukawa-type interaction, where we presented the uncertainty of the compact star observables taking into account the quantum fluctuation in the FRG framework.
In this talk we present a similar study based on a realistic, Walecka type model, with several physical parameters. We present the scaling and the uncertainty of the mass and radius of the compact stars, which exhibit linear connection between them. Comparison with astrophysical observation data will be also presented.
