Abstract: The effect of the symmetry energy on the properties of compact stars is discussed. It is shown that, for stars with masses above 1 Modot, the radius of the star varies linearly with the symmetry energy slope L. The hyperon-meson couplings are chosen according to experimental values of the hyperon nuclear matter potentials, and possible uncertainties are considered. It is shown that a softer symmetry energy gives rise to stars with less hyperons and smaller radius. Hyperon-meson couplings may also have a strong effect on the mass of the star.
