Non-relativistic stellar structure in the Fierz--Pauli theory and generic linear massive gravity
Tomoya Tachinami, Yuuiti Sendouda
We study the structure of static spherical stars composed of non-relativistic matter in linear massive gravity with or without the Fierz-Pauli (FP) tuning. Adopting a polytropic eq…

Non-relativistic stellar structure in higher-curvature gravity: systematic construction of solutions to the modified Lane-Emden equations
Shinpei Tonosaki, Tomoya Tachinami, Yuuiti Sendouda
We study the structure of static spherical stars made up of a non-relativistic polytropic fluid in linearized higher-curvature theories of gravity (HCG). We first formulate the mod…

Gravitational-wave polarizations in generic linear massive gravity and generic higher-curvature gravity
Tomoya Tachinami, Shinpei Tonosaki, Yuuiti Sendouda
We study the polarizations of gravitational waves (GWs) in two classes of extended gravity theories. First, we formulate the polarizations in linear massive gravity (MG) with gener…
