Hydrodynamics of Coalescing Binary Neutron Stars: Ellipsoidal Treatment
Dong Lai, Stu Shapiro
We employ an approximate treatment of dissipative hydrodynamics in three dimensions to study the coalescence of binary neutron stars driven by the emission of gravitational waves.…
Gravitational Radiation from Rapidly Rotating Nascent Neutron Stars
Dong Lai, Stu Shapiro
We study the secular evolution and gravitational wave signature of a newly-formed, rapidly rotating neutron star. The neutron star may arise from core collapse in a massive star or…
Resonant Oscillations and Tidal Heating in Coalescing Binary Neutron Stars
Dong Lai
Tidal interaction in a coalescing neutron star binary can resonantly excite the g-mode oscillations of the neutron star when the frequency of the tidal driving force equals the int…
Hydrodynamics of Rotating Stars and Close Binary Interactions: Compressible Ellipsoid Models
Dong Lai, Frederic A. Rasio, Stuart L. Shapiro
We develop a new formalism to study the dynamics of fluid polytropes in three dimensions. The stars are modeled as compressible ellipsoids and the hydrodynamic equations are reduce…
