Correlations between charge radii differences of mirror nuclei and stellar observables

NUCLEAR STRUCTURE ^34,36S, ^34,38Ar, ³⁶Ca, ³⁸Ca, ⁵⁴Fe, ⁵⁴Ni; calculated rms proton radii differences of mirror nuclei and correlation with neutron skin thickness, slope of the symmetry energy, tidal deformability and neutron star radius correlation to charge radii difference in mirror pairs and neutron skin thickness. Investigated isospin-symmetry breaking effect leading to a linear correlation between the proton rms radii difference in mirror pairs and neutron skin thickness. Simple effective interaction (SEI) finite-range model.
