The Death of Compact Binary Stars
Astrophysics and Space Science, 1997Merging rates for compact binaries (double neutron stars or black holes) are calculated based on modern concepts of binary star evolution. It is found that the first laser interferometers, with rms sensitivities of 10-21 at a frequency of 100 Hz, can detect 10-700 black holes and only ∼1 neutron star coalescences in a 1-year integration time.

First Constraints on Compact Binary Environments from LIGO-Virgo Data.
Physical Review Letters, 2023The LIGO-Virgo analyses of signals from compact binary mergers observed so far have assumed isolated binary systems in a vacuum, neglecting the potential presence of astrophysical environments.

Astrophysical Journal Letters
Binary stars and their interactions shape the formation of compact binaries, supernovae, and gravitational-wave sources. The efficiency of mass transfer—the fraction of mass retained by the accretor during binary interaction—is a critical parameter that ...

Chirping compact stars: gravitational radiation and detection degeneracy with binaries
Journal of Cosmology and Astroparticle Physics, 2023Abstract Compressible, Riemann S-type ellipsoids can emit gravitational waves (GWs) with a chirp-like behavior (hereafter chirping ellipsoids, CELs). We show that the GW frequency-amplitude evolution of CELs (mass ∼ 1 M⊙, radius ∼ 103 km, polytropic equation of state with index n ≈ 3) is indistinguishable from that emitted by double ...

Interactive stars: Normal and compact stars in close binaries
AIP Conference Proceedings, 1990The missions planned for the 1990’s will greatly expand our knowledge of close binary systems and the physical phenomena that can be studied in a member of a close binary, from stellar active regions to the highest density black hole candidates known.

Fractions of Compact Object Binaries in Star Clusters: Theoretical Predictions
Research in Astronomy and Astrophysics, 2023Abstract The binary population in field stars and star clusters contributes to the formation of gravitational wave (GW) sources. However, the fraction of compact-object binaries (CBs), which is an important feature parameter of binary populations, is still difficult to measure and very uncertain.

Accretion effects on compact members of binary stars
Journal of Astrophysics and Astronomy, 1988We explore the change in the period of axial rotation and in the radius of a magnetized compact star in a binary system, induced by the accretion on it of mass with angular momentum from the surface of its non-compact companion. No specific assumption is made concerning the accretion model, and the primary’s interior is described by the Fermi-Dirac ...

Compact Stars In and Out of Binaries
1995The Very Large Telescope will allow us to determine more orbital periods and component masses of cataclysmic variables, low-mass X-ray binaries and high-mass X-ray binaries. These are required to put evolutionary models for these systems on a quantitative footing.
