Moment of inertia - mass universal relations for neutron stars in scalar-tensor theory with self-interacting massive scalar field
Dimitar Popchev, Kalin V. Staykov, Daniela D. Doneva +1
We are investigating universal relations between different normalisations of the moment of inertia and the compactness of neutron stars in slow rotation approximation. We study the…

Static and slowly rotating neutron stars in scalar-tensor theory with self-interacting massive scalar field
Kalin V. Staykov, Dimitar Popchev, Daniela D. Doneva +1
Binary pulsar observations and gravitational wave detections seriously constrained scalar-tensor theories with massless scalar field allowing only small deviations from general rel…

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…
