Gravitational solitons and vacuum metrics in five-dimensional Lovelock gravity
C. Garraffo, G. Giribet, E. Gravanis +1
Junction conditions for vacuum solutions in five-dimensional Einstein-Gauss-Bonnet gravity are studied. We focus on those cases where two spherically symmetric regions of space-tim…
Dynamical black holes with symmetry in Einstein-Gauss-Bonnet gravity
Masato Nozawa, Hideki Maeda
We explore various aspects of dynamical black holes defined by a future outer trapping horizon in -dimensional Einstein-Gauss-Bonnet gravity. In the present paper, we ass…
Static black hole solutions with a self interacting conformally coupled scalar field
Gustavo Dotti, Reinaldo J. Gleiser, Cristian Martinez
We study static, spherically symmetric black hole solutions of the Einstein equations with a positive cosmological constant and a conformally coupled self interacting scalar field.…
Generalized Misner-Sharp quasi-local mass in Einstein-Gauss-Bonnet gravity
Hideki Maeda, Masato Nozawa
We investigate properties of a quasi-local mass in a higher-dimensional spacetime having symmetries corresponding to the isomertries of an -dimensional maximally symmetric s…
Incompressible fluid inside an astrophysical black hole?
Fabrizio Canfora
It is argued that under natural hypothesis the Fermions inside a black hole formed after the collapse of a neutron star could form a non compressible fluid (well before reaching th…
Braneworld dynamics in Einstein-Gauss-Bonnet gravity
Hideki Maeda, Varun Sahni, Yuri Shtanov
We discuss the cosmological evolution of a braneworld in five dimensional Gauss-Bonnet gravity. Our discussion allows the fifth (bulk) dimension to be space-like as well as time-li…
