Einstein-Maxwell-Dilaton-Axion mass formulas for black holes with struts and strings
Dmitri Gal'tsov, Gérard Clément, Igor Bogush
Mass formulas are obtained for stationary axisymmetric solutions of the Einstein-Maxwell dilaton-axion theory, which have a regular rod structure on the axis of symmetry. Asymptoti…
Palatini kinetic scalar-tensor theory: analytical and numerical solutions
D. V. Gal'tsov, D. S. Bushuev
We investigate static spherically symmetric solutions in the Palatini kinetically coupled scalar-tensor theory, which reduces to gravity minimally coupled to a scalar field in Eins…
Photon regions in stationary axisymmetric spacetimes and umbilic conditions
Kirill Kobialko, Dmitri Gal'tsov
We present the fundamentals of the recently proposed geometric description of photon regions in terms of foliation into fundamental photon hypersurfaces, which satisfies the umbili…
Killing tensors in foliated spacetimes and photon surfaces
Kirill Kobialko, Igor Bogush, Dmitri Gal'tsov
We discuss a recently proposed geometric method for constructing a nontrivial Killing tensor of rank two in a foliated spacetime of codimension one that lifts trivial Killing tenso…
Odd-dimensional gravitational waves from a binary system on a three-brane
D. V. Gal'tsov, M. Khlopunov
We consider gravitational radiation in the presence of non-compact extra dimensions. If their number is odd, all spacetime becomes odd-dimensional and formation of gravitational ra…
Killing tensors and photon surfaces in foliated spacetimes
Kirill Kobialko, Igor Bogush, Dmitri Gal'tsov
We present a purely geometric method for constructing a rank two Killing tensor in a spacetime with a codimension one foliation that lifts the trivial Killing tensors from slices t…
