On the stability of spherically symmetric spacetimes in metric f(R) gravity
Kimmo Kainulainen, Daniel Sunhede
We consider stability properties of spherically symmetric spacetimes of stars in metric f(R) gravity. We stress that these not only depend on the particular model, but also on the…
Spherically symmetric spacetimes in f(R) gravity theories
Kimmo Kainulainen, Johanna Piilonen, Vappu Reijonen +1
We study both analytically and numerically the gravitational fields of stars in f(R) gravity theories. We derive the generalized Tolman-Oppenheimer-Volkov equations for these theor…
The interior spacetimes of stars in Palatini f(R) gravity
Kimmo Kainulainen, Vappu Reijonen, Daniel Sunhede
We study the interior spacetimes of stars in the Palatini formalism of f(R) gravity and derive a generalized Tolman-Oppenheimer-Volkoff and mass equation for a static, spherically…
Dark Energy, Scalar-Tensor Gravity and Large Extra Dimensions
Kimmo Kainulainen, Daniel Sunhede
We explore in detail a dilatonic scalar-tensor theory of gravity inspired by large extra dimensions, where a radion field from compact extra dimensions gives rise to quintessence i…
