Breakdown of I-Love-Q universality in rapidly rotating relativistic stars
Daniela D. Doneva, Stoytcho S. Yazadjiev, Nikolaos Stergioulas +1
It was shown recently, that normalized relations between the moment of inertia (I), the quadrupole moment (Q) and the tidal deformability (Love number) exist and for slowly-rotatin…
Rapidly rotating neutron stars in scalar-tensor theories of gravity
Daniela D. Doneva, Stoytcho S. Yazadjiev, Nikolaos Stergioulas +1
We present the field equations governing the equilibrium of rapidly rotating neutron stars in scalar-tensor theories of gravity, as well as representative numerical solutions. The…
Gravitational wave asteroseismology of fast rotating neutron stars with realistic equations of state
Daniela D. Doneva, Erich Gaertig, Kostas D. Kokkotas +1
In the present paper we study the oscillations of fast rotating neutron stars with realistic equations of state (EoS) within the Cowling approximation. We derive improved empirical…
