Stability of disformally coupled accretion disks
Tomi Koivisto, Hannu J. Nyrhinen
The no-hair theorem postulates that the only externally observable properties of a black hole are its mass, its electric charge, and its angular momentum. In scalar-tensor theories…
ADM Analysis of Gravity Models within the Framework of Bimetric Variational Formalism
Alexey Golovnev, Mindaugas Karciauskas, Hannu J. Nyrhinen
Bimetric variational formalism was recently employed to construct novel bimetric gravity models. In these models an affine connection is generated by an additional tensor field whi…
Binary systems in Palatini-f(R) gravity
Kari Enqvist, Tomi Koivisto, Hannu J. Nyrhinen
We consider compact binary systems in f(R) gravity theories in the Palatini approach and calculate the post-Newtonian parameters to the 1.5PN order using the method of Direct Integ…
