Universal I-Q relations for rapidly rotating neutron and strange stars in scalar-tensor theories
Daniela D. Doneva, Stoytcho S. Yazadjiev, Kalin V. Staykov +1
We study how rapid rotation influences the relation between the normalized moment of inertia and quadrupole moment for scalarized neutron stars. The questions o…
Slowly rotating neutron and strange stars in gravity
Kalin V. Staykov, Daniela D. Doneva, Stoytcho S. Yazadjiev +1
In the present paper we investigate self-consistently slowly rotating neutron and strange stars in R-squared gravity. For this purpose we first derive the equations describing the…
Orbital and epicyclic frequencies around rapidly rotating compact stars in scalar-tensor theories of gravity
Daniela D. Doneva, Stoytcho S. Yazadjiev, Nikolaos Stergioulas +2
We study the orbital and epicyclic frequencies of particles orbiting around rapidly rotating neutron stars and strange stars in a particular scalar-tensor theory of gravity. We fin…
