Neutron stars in the theory of gravity with nonminimal derivative coupling and realistic equations of state
P. E. Kashargin, A. A. Lebedev, S. V. Sushkov
We numerically construct compact stars in the scalar-tensor theory of gravity with non-minimal derivative coupling of a scalar field to the curvature and nonzero cosmological const…
Possible wormholes in a Friedmann universe
Kirill A. Bronnikov, Pavel E. Kashargin, Sergey V. Sushkov
We study the properties of evolving wormholes able to exist in a closed Friedmann dust-filled universe and described by a particular branch of the well-known Lemaıtre-Tolman-Bondi…
Anti-de Sitter neutron stars in the theory of gravity with nonminimal derivative coupling
Pavel E. Kashargin, Sergey V. Sushkov
We consider neutron star configurations in the scalar-tensor theory of gravity with the coupling between the kinetic term of a scalar field and the Einstein tensor (such the model…
Magnetized dusty black holes and wormholes
Kirill A. Bronnikov, Pavel E. Kashargin, Sergey V. Sushkov
We consider the generalized Tolman solution of general relativity, describing the evolution of a spherical dust cloud in the presence of an external electric or magnetic field. The…
Collapsing Wormholes Sustained by Dustlike Matter
Pavel E. Kashargin, Sergey V. Sushkov
It is well known that static wormhole configurations in general relativity (GR) are possible only if matter threading the wormhole throat is "exotic"---i.e., violates a number of e…
Rotating thin-shell wormhole from glued Kerr spacetimes
P. E. Kashargin, S. V. Sushkov
We construct a model of a rotating wormhole made by cutting and pasting two Kerr spacetimes. As a result, we obtain a rotating thin-shell wormhole with exotic matter at the throat.…
