论文摘要
我们在$ r^2 $重力中为爱因斯坦框架中的中子星构建了准模式，考虑到子NEV范围内的标量质量。特别是，我们研究了基本四极流体F模型和偶极液F模型。然后，使用六个方程式覆盖了核子，超子和夸克的物质含量，然后我们提出了四极F-Modes和偶极子F模型的普遍关系。偶极子F模型是超长的，对于较低的标量质量，它们的频率与相应的康普顿波长成反比。
We construct quasinormal modes for neutron stars in $R^2$ gravity in the Einstein frame, considering scalar masses in the sub-neV range. In particular, we investigate the fundamental quadrupole fluid f-modes and the dipole fluid F-modes. Employing six equations of state covering matter content with nucleons, hyperons, and quarks, we then propose universal relations for the quadrupole f-modes and dipole F-modes. The dipole F-modes are ultra-long lived and, for the lower scalar masses, their frequencies are inversely proportional to the corresponding Compton wavelength.
