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…
