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…
Slowly rotating neutron stars in scalar-tensor theories with a massive scalar field
Stoytcho S. Yazadjiev, Daniela D. Doneva, Dimitar Popchev
In the scalar-tensor theories with a massive scalar field the coupling constants, and the coupling functions in general, which are observationally allowed, can differ significantly…
Moment of inertia -- compactness universal relations in scalar-tensor theories and gravity
Kalin V. Staykov, Daniela D. Doneva, Stoytcho S. Yazadjiev
We are investigating universal relations between different normalisations of the moment of inertia and the compactness of neutron and strange stars. Slowly rotating as well as rapi…
Stability and Quasinormal Modes of Black holes in Tensor-Vector-Scalar theory: Scalar Field Perturbations
Paul D. Lasky, Daniela D. Doneva
The imminent detection of gravitational waves will trigger precision tests of gravity through observations of quasinormal ringing of black holes. While General Relativity predicts…
