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…
Detecting classical nova-like explosions with LISA
Ethan McKeever, Shu Yan Lau, Hang Yu +1
Gravitational waves from close binary white dwarfs will form the bulk of measurements obtained by the Laser Interferometer Space Antenna (LISA). Previous studies have highlighted t…
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…
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…
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…
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…
