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…
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…
