考虑非牛顿引力，研究了用超软状态方程（EOS）描述的中子星轴向w模的本征频率。结果表明，在相同的恒星质量下，我们的模型中wI和wI2的频率低于典型的eos（如APR）；频率随恒星质量的增加而增加，这与典型的eos相反。这些特征可以为未来验证超软对称能和非牛顿引力提供一个探针。此外，我们的模型还具有质量尺度本征频率作为紧度函数的普遍特性。
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.
