Hamilton-Jacobi formalism for k-inflation
Rong-Jia Yang, Ming Liu
We consider a type of k-inflation under the Hamilton-Jacobi approach. We calculate various observables such as the scalar power spectrum, the tensor-to-scalar ratio, the scalar spe…
Types of the geodesic motions in Kerr-Sen-AdS spacetime
Ziqiang Cai, Tong-Yu He, Wen-Qian Wang +2
We consider the geodesic motions in the Kerr-Sen-AdS spacetime. We obtain the equations of motion for light rays and test particles. Using the parametric diagrams, we shown som…
Thin accretion disks around a black hole in Einstein-Aether-scalar theory
Tong-Yu He, Ziqiang Cai, Rong-Jia Yang
We consider the accretion process in the thin disk around a supermassive black hole in Einstein-aether-scalar theory. We probe the effects of the model parameter on the physical pr…
Accretion of the Vlasov gas onto a Schwarzschild-like black hole
Ziqiang Cai, Rong-Jia Yang
We consider spherical steady accretion of the relativistic Vlasov gas onto a Schwarzschild-like black hole. We determine the expressions for the particle current density and accret…
Adiabatic accretion onto black holes in Einstein-Maxwell-scalar theory
Haiyuan Feng, Miao Li, Gui-Rong Liang +1
We study the adiabatic accretion process of ordinary baryonic gas onto spherically symmetric black holes in Einstein-Maxwell-scalar theory, with two parameters and in the c…
Exact solution for accretion onto a moving charged dilaton black hole
Rong-Jia Yang, Yinan Jia, Lei Jiao
We present an analytic solution for accretion of a gaseous medium with adiabatic equation of state onto a charged dilaton black hole which moves at a constant velocity. We determin…
