Relativistic stars in f(R) and scalar-tensor theories
E. Babichev, D. Langlois
We study relativistic stars in the context of scalar tensor theories of gravity that try to account for the observed cosmic acceleration and satisfy the local gravity constraints v…
Recovering General Relativity from massive gravity
E. Babichev, C. Deffayet, R. Ziour
We obtain static, spherically symmetric, and asymptotically flat numerical solutions of massive gravity with a source. Those solutions show, for the first time explicitly, a recove…
k-Mouflage gravity
E. Babichev, C. Deffayet, R. Ziour
We introduce a large class of scalar-tensor theories where gravity becomes stronger at large distances via the exchange of a scalar that mixes with the graviton. At small distances…
Relativistic stars in f(R) gravity
E. Babichev, D. Langlois
We study the strong gravity regime in viable models of so-called f(R) gravity that account for the observed cosmic acceleration. In contrast with recent works suggesting that very…
The Vainshtein mechanism in the Decoupling Limit of massive gravity
E. Babichev, C. Deffayet, R. Ziour
We investigate static spherically symmetric solutions of nonlinear massive gravities. We first identify, in an ansatz appropriate to the study of those solutions, the analog of the…
