Abstract:

The eigen-frequencies of the axial w-modes of neutron star described by a super-soft equation of state (EOS) are investigated, by considering the non-Newtonian gravity. The results show that at the same stellar mass, the frequencies of wI and wI2 for our model are lower than that of the typical EOSs (such as APR); and the frequencies increase with the stellar masses, which is contrary to that of the typical EOSs. These characters may provide a probe to testify the super soft symmetry energy and the non-Newtonian gravity in the future. Moreover, our model also has the universal behavior of the mass-scaled eigen-frequencies as a function of the compactness.
