论文摘要
标量调节理论允许中子星的准模式丰富。标量场的存在允许极性单极和偶极子辐射，以及标量场引导的额外更高的多极模式。在这里，我们提出了这些标量为最低多极端的标量为$ ϕ $ modes，$ l = 0 $，1和2用于Brans-dicke类型的无质量标量张量理论，由$ r^2 $理论激励，并与通常相对论的微型耦合标量场相比。我们考虑一组六个现实的状态方程，并为模式提取普遍关系。
Scalar-tensor theories allow for a rich spectrum of quasinormal modes of neutron stars. The presence of the scalar field allows for polar monopole and dipole radiation, as well as for additional higher multipole modes led by the scalar field. Here we present these scalar-led $ϕ$-modes for the lowest multipoles, $l=0$, 1 and 2 for a massless scalar-tensor theory of the Brans-Dicke type, motivated by $R^2$ theory, and compare with those of a minimally coupled scalar field in general relativity. We consider a set of six realistic equations of state and extract universal relations for the modes.
