Anisotropic Fluid Model for Massive Boson Stars: Spherically Symmetric Configurations
Ethan McKeever, Victor Guedes, Shu Yan Lau +1
Boson stars are among the best-studied exotic compact objects and constitute one of the few black-hole mimickers for which both the formation mechanism and dynamical behavior can b…
Nonlinear hydrodynamics in spinning neutron stars: Theoretical universal relations and equilibrium solutions
Hang Yu, Giorgio Nicolini, Shu Yan Lau +6
We study tides during the inspiral of a binary neutron star system, including nonlinear hydrodynamical interactions. Using an affine approximation that treats the perturbed neutron…
Irregular Repeating Tidal Disruption Events due to Diffusive Tides
Shu Yan Lau, Ethan McKeever, Hang Yu
A repeating partial tidal disruption event (rpTDE) is typically modeled as a star on a bound orbit that is partially disrupted by a massive black hole (MBH) at each pericenter pass…
Spacetime Quasi-normal Mode Oscillations of Anisotropic Neutron Stars
Jihao Yu, Victor Guedes, Shu Yan Lau +2
Neutron star asteroseismology offers a unique opportunity to probe nuclear physics through stellar oscillations. Although the pressure inside of a neutron star is typically assumed…
Gravitational-Wave Constraints on Neutron-Star Pressure Anisotropy via Universal Relations
Victor Guedes, Siddarth Ajith, Shu Yan Lau +1
Neutron stars may exhibit pressure anisotropy arising from various physical mechanisms, such as elasticity, magnetic fields, viscosity, and superfluidity. We compute the tidal defo…
Universal Relations for Elastic Hybrid Stars and Quark Stars
Chun-Ming Yip, Shu Yan Lau, Kent Yagi
Some compact stars may contain deconfined quark matter, forming hybrid stars or quark stars. If the quark matter forms an inhomogeneous condensate in the crystalline color supercon…
Dynamical tide modified Roche limit in eccentric, asynchronous binaries
Hang Yu, Shu Yan Lau, Ethan Mckeever +2
The Roche limit, or the threshold separation within which a celestial object (the donor) M cannot remain in a stable configuration due to a companion's tidal field, has been well e…
Gravitational Radiation-Driven Chaotic Tide in a White Dwarf-Massive Black Hole Binary as a Source of Repeating X-ray Transients
Shu Yan Lau, Hang Yu
Eccentric white dwarf-massive black hole binaries can potentially source some extreme X-ray transients, including the recently observed quasi-periodic X-ray eruptions and tidal dis…
Effective-one-body model for coalescing binary neutron stars: Incorporating tidal spin and enhanced radiation from dynamical tides
Hang Yu, Shu Yan Lau
Tidal interactions in a coalescing binary neutron star (BNS) or neutron star-black hole (NSBH) system driven by gravitational wave (GW) radiation contain precious information about…
New modeling for hybrid stars with an elastic quark core
Zoey Zhiyuan Dong, Shu Yan Lau, Kent Yagi
Heavy neutron stars may contain solid quark cores as motivated by, e.g. the crystalline color superconducting phase, forming elastic hybrid stars (HSs). Many previous studies assum…
Astrophysical systematics on testing general relativity with gravitational waves from galactic double white dwarfs
Shu Yan Lau, Kent Yagi, Phil Arras
Gravitational waves have been shown to provide new constraints on gravitational theories beyond general relativity (GR), especially in the strong field regime. Gravitational wave s…
Love-C relations for elastic hybrid stars
Zoey Zhiyuan Dong, Joshua Cole Faggert, Shu Yan Lau +1
Neutron stars (NSs) provide a unique laboratory to study matter under extreme densities. Recent observations from gravitational and electromagnetic waves have enabled constraints o…
The broadening of universal relations at the birth and death of a neutron star
Victor Guedes, Shu Yan Lau, Cecilia Chirenti +1
Certain relations among neutron-star observables that are insensitive to the equation of state are known to exist. Such universal relations have been shown to be valid for cold and…
Astrophysical Parameter Inference on Accreting White Dwarf Binaries using Gravitational Waves
Sophia Yi, Shu Yan Lau, Kent Yagi +1
Accreting binary white dwarf systems are among the sources expected to emanate gravitational waves that the Laser Interferometer Space Antenna (LISA) will detect. We investigate ho…
Periastron precession effect of -mode dynamical tides on gravitational waves from eccentric double white dwarfs
Shu Yan Lau, Kent Yagi, Phil Arras
The dynamical tide can play an important role in the orbital motion of close eccentric double white dwarf binaries. As the launching of the space-based gravitational-wave detector,…
Probing hybrid stars with gravitational waves via interfacial modes
Shu Yan Lau, Kent Yagi
One of the uncertainties in nuclear physics is whether a phase transition between hadronic nuclear matter to quark matter exists in supranuclear matter equations of state. Such a f…
Two-layer compact stars with crystalline quark matter: Screening effect on the tidal deformability
S. Y. Lau, P. T. Leung, L. -M. Lin
(Abridged) It is well known that the tidal deformability of a compact star carries important information about the interior equation-of-state (EOS) of the star. The first gravitati…
Tidal deformations of compact stars with crystalline quark matter
S. Y. Lau, P. T. Leung, L. -M. Lin
We study the tidal deformability of bare quark stars and hybrid compact stars composed of a quark matter core in general relativity, assuming that the deconfined quark matter exist…
