Accessing universal relations of binary neutron star waveforms in massive scalar-tensor theory
Alan Tsz-Lok Lam, Yong Gao, Hao-Jui Kuan +3
We investigate how the quasi-universal relations connecting tidal deformability with gravitational waveform characteristics and/or properties of individual neutron stars that were…
The Last Three Seconds: Packed Message delivered by Tides in Binary Neutron Star Mergers
Hao-Jui Kuan, Kostas D. Kokkotas
It is known that the leading-order tidal effects in gravitational waveforms can be quantified by tidal deformability, while higher order terms, e.g., harmonic overtones of Love num…
Binary neutron star mergers in massive scalar-tensor theory: Quasi-equilibrium states and dynamical enhancement of the scalarization
Hao-Jui Kuan, Karim Van Aelst, Alan Tsz-Lok Lam +1
We study quasi-equilibrium sequences of binary neutron stars in the framework of Damour-Esposito-Farese-type scalar-tensor theory of gravity with a massive scalar field, paying par…
Dynamical Scalarization during Neutron Star Mergers in scalar-Gauss-Bonnet Theory
Hao-Jui Kuan, Alan Tsz-Lok Lam, Daniela D. Doneva +3
In certain classes of the scalar-Gauss-Bonnet theory strong spacetime curvature in the vicinity of neutron stars and black holes can spontaneously trigger scalarization in the comp…
