Resonant Oscillations and Tidal Heating in Coalescing Binary Neutron Stars
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 intrinsic g-mode frequencies. We study the g-mode oscillations of cold neutron stars using recent microscopic nuclear equations of state, where we determine self-consistently the sound speed and Brunt-Väisälä frequency i...

متن کاملAnalytic modeling of tidal effects in the relativistic inspiral of binary neutron stars.
To detect the gravitational-wave (GW) signal from binary neutron stars and extract information about the equation of state of matter at nuclear density, it is necessary to match the signal with a bank of accurate templates. We present the two longest (to date) general-relativistic simulations of equal-mass binary neutron stars with different compactnesses, C=0.12 and C=0.14, and compare them wi...
متن کاملAn Observational Study of Tidal Synchronization in Solar-type Binary Stars in the Open Clusters
We present rotation periods for the solar-type primary stars in 13 close (a . 5 AU) single-lined spectroscopic binaries with known orbital periods (P ) and eccentricities (e). All binaries are members of the open clusters M35 (NGC2168; ∼ 150 Myr) and M34 (NGC1039; ∼ 250 Myr). The binary orbital parameters and the rotation periods of the primary stars were determined from time-series spectroscop...
متن کاملTidal Break-up of Binary Stars at the Galactic Center and Its Consequences
The tidal breakup of binary star systems by the supermassive black hole (SMBH) in the center of the galaxy has been suggested as the source of both the observed sample of hypervelocity stars (HVSs) in the halo of the Galaxy and the S-stars that remain in tight orbits around Sgr A*. Here, we use a postNewtonian N-body code to study the dynamics of main-sequence binaries on highly elliptical boun...
