Neutron star solutions with curvature induced scalarization in the extended Gauss-Bonnet scalar-tensor theories
Daniela D. Doneva, Stoytcho S. Yazadjiev
In the present paper we study models of neutron stars in a class of extended scalar-tensor Gauss-Bonnet (ESTGB) theories for which the scalar degree of freedom is exited only in th…
New Gauss-Bonnet black holes with curvature induced scalarization in the extended scalar-tensor theories
Daniela D. Doneva, Stoytcho S. Yazadjiev
In the present paper we consider a class of extended scalar-tensor-Gauss-Bonnet (ESTGB) theories for which the scalar degree of freedom is excited only in the extreme curvature reg…
Universal Relations and Alternative Gravity Theories
Daniela D. Doneva, George Pappas
This is a review with the ambitious goal of covering the recent progress in: 1) universal relations (in general relativity and alternative theories of gravity), and 2) neutron star…
Oscillation modes of rapidly rotating neutron stars in scalar-tensor theories of gravity
Stoytcho S. Yazadjiev, Daniela D. Doneva, Kostas D. Kokkotas
We perform the first study of the oscillation frequencies of rapidly rotating neutron stars in alternative theories of gravity, focusing mainly on the fundamental -modes. We con…
