Images of the accretion disk in Hybrid metric-Palatini gravity
P. I. Dyadina, N. A. Avdeev
In this paper we obtain and study images of accretion disks around static spherically symmetric black holes in hybrid metric-Palatini gravity. We use Novikov-Thorne thin-disk model…
Thin accretion disk signatures in hybrid metric-Palatini gravity
P. I. Dyadina, N. A. Avdeev
In the present work, accretion onto a static spherically symmetric black hole in the hybrid metric-Palatini gravity is considered. The Novikov-Thorne model for a relativistic thin…
Ruling out an inflation driven by a power law potential: kinetic coupling does not help
N. Avdeev, A. Toporensky
We demonstrate that the latest constraints on inflationary observables, namely the tensor-to-scalar ratio and the scalar spectral index , from the Cosmic Background Rad…
On viability of inflation in non-minimal kinetic coupling theory
N. Avdeev, A. Toporensky
We consider initial conditions for inflation in non-minimal kinetic coupling theory. If inflation is driven solely by kinetic term with no potential, the resulting number of e-fold…
Test of hybrid metric-Palatini f(R)-gravity in binary pulsars
N. Avdeev, P. Dyadina, S. Labazova
We developed the parameterized post-Keplerian formalism for hybrid metric-Palatini -gravity. We obtained analytical expressions in the generel eccentric case for four PPK par…
Horndeski gravity without screening in binary pulsars
P. I. Dyadina, N. A. Avdeev, S. O. Alexeyev
We test the subclasses of Horndeski gravity without Vainshtein mechanism in the strong field regime of binary pulsars. We find the rate of energy losses via the gravitational radia…
